The present teaching relates to a leaning vehicle.
There has been known a standing-type leaning vehicle in which a driver places the left foot on a left foot step and the right foot on a right foot step. As such a leaning vehicle, Non-patent Document 1, for example, discloses a motorcycle with a license plate, a taillight and direction signals provided at the center of a rear portion of the vehicle.
In the motorcycle of Non-patent Document 1, the left foot step and the right foot step are individually located between a front wheel and a rear wheel in the front-rear direction of the motorcycle and fixed to a vehicle body frame.
In the motorcycle of Non-patent Document 1, the license plate, the taillight and the direction signals are attached to a frame extending upward from a rear frame. Thus, the license plate, the taillight and the direction signals are located further upward than an axle of the rear wheel.
Patent Document 1 discloses a vehicle including a vehicle body frame, a left front wheel, a right front wheel, and a linkage mechanism located further upward than the left front wheel and the right front wheel and configured to shift positions of the left front wheel and the right front wheel relative to the vehicle body frame so that the vehicle body frame leans to the left or to the right of the vehicle. The linkage mechanism includes an upper cross member and a lower cross member extending in the left-right direction, a right side member rotatably supporting right ends of the upper cross member and the lower cross member, and a left side member rotatably supporting left ends of the upper cross member and the lower cross member. An intermediate portion of each of the upper cross member and the lower cross member is supported by the vehicle body frame in front of a steering shaft.
The upper cross member and the lower cross member are supported by the vehicle body frame such that the upper and lower cross members are rotatable about axes extending substantially in the front-rear direction of the vehicle body frame. The upper and lower cross members rotate with respect to the vehicle body frame by interlocking with leaning of the vehicle body frame, which causes shift in relative positions of the two front wheels in the top-bottom direction of the vehicle body frame. The upper and lower cross members are provided further upward than the two front wheels in the top-bottom direction of the vehicle body frame in a state where the vehicle body frame is upright.
The vehicle disclosed in Patent Document 1 includes a load transfer mechanism configured to include a left-foot-placing face on which the left foot of a driver of the vehicle is placed and a right-foot-placing face on which the right foot of the driver is placed, and configured such that a load is allowed to be transferred to a left portion of the linkage mechanism through one of the left-foot-placing face or the right-foot-placing face and that a load is allowed to be transferred to a right portion of the linkage mechanism through the other of the left-foot-placing face or the right-foot-placing face.
In the vehicle disclosed in Patent Document 1, the driver starts driving the vehicle with the left foot placed on a left-foot-placing part (left foot step) and the right foot placed on a right-foot-placing part (right foot step).
Therefore, there is a demand for a configuration that allows for easy placement of the left foot on the left foot step and easy placement of the right foot on the right foot step in a vehicle including a left front wheel and a right front wheel.
It is therefore an object of the present teaching to obtain a configuration that allows for easy placement of the left foot on a left foot step and easy placement of the right foot on a right foot step in a leaning vehicle including a left front wheel and a right front wheel.
The inventors of the present teaching studied a configuration that allows the left foot to be easily placed on a left foot step and the right foot to be easily placed on a right foot step in a leaning vehicle including a left front wheel and a right front wheel.
Through an intensive study, the inventors of the present teaching arrived at the configuration as described below.
A leaning vehicle according to one embodiment of the present teaching is configured to lean leftward when turning to left and lean rightward when turning to right and includes: a vehicle body frame; a left front wheel located at left of the vehicle body frame in a left-right direction of the vehicle body frame; a right front wheel located at right of the vehicle body frame in the left-right direction of the vehicle body frame; a rear wheel located between the left front wheel and the right front wheel when the vehicle body frame is seen in a front-rear direction of the vehicle body frame, and located further rearward than the left front wheel and the right front wheel in the front-rear direction of the vehicle body frame; a linkage mechanism supported by a front portion of the vehicle body frame, to allow the vehicle body frame to lean leftward or rightward in the left-right direction of the vehicle body frame; a left foot step including a left-foot-placing face for a left foot of a driver to be placed thereon, at least a part of the left foot step being located rearward of the left front wheel; a right foot step including a right-foot-placing face for a right foot of the driver to be placed thereon, at least a part of the right foot step being located rearward of the right front wheel; and a rear fender covering at least a part of an upper portion of the rear wheel. The leaning vehicle further includes rear equipment (i.e., a rear device) supported by a rear portion of the vehicle body frame and being separate from the rear fender. The rear device is so located that in a front-rear direction of the leaning vehicle, a distance from a rear end of the left foot step to a front end of the rear device is greater than a half of a length of the left foot step, and a distance from a rear end of the right foot step to the front end of the rear device is greater than a half of a length of the right foot step. The rear device is so located that in a top-bottom direction of the leaning vehicle, a height of an upper end of the rear device from the left-foot-placing face of the left foot step (i.e., a distance between the upper end of the rear device and the left-foot-placing face of the left foot step) is less than a height of the left-foot-placing face of the left foot step from a ground surface (i.e., a distance between the left-foot-placing face of the left foot step and the ground surface), and a height of the upper end of the rear device from the right-foot-placing-face of the right foot step (i.e., a distance between the upper end of the rear device and the right-foot-placing-face of the right foot step) is less than a height of the right-foot-placing face of the right foot step from the ground surface (i.e., a distance between the right-foot-placing face of the right foot step and the ground surface). In a left-right direction of the leaning vehicle, the rear device is located between a center of the left foot step and a center of the right foot step when the leaning vehicle is seen from rear.
When a driver rides on the leaning vehicle, the driver rides on the leaning vehicle from the rear. When the driver rides on the leaning vehicle from the rear, the driver needs to place the feet at a left position and a right position of the rear wheel of the leaning vehicle. Thus, it is necessary to secure spaces which allow the driver's feet to be placed therein at the left position and the right position of the rear wheel of the leaning vehicle.
In the above-described configuration, therefore, the rear device is located at a position apart in the front-rear direction from the left foot step and the right foot step, and located between the center in the left-right direction of the left foot step and the center in the left-right direction of the right foot step when the leaning vehicle is seen from the rear. Accordingly, the spaces for the driver's feet to be placed therein can be secured at the left and the right of the rear wheel.
The height of the upper end of the rear device in the top-bottom direction from the left-foot-placing face of the left foot step is less than the height of the left-foot-placing face of the left foot step in the top-bottom direction from the ground surface, and the height of the upper end of the rear device in the top-bottom direction from the right-foot-placing-face of the right foot step is less than the height of the right-foot-placing face of the right foot step in the top-bottom direction from the ground surface. This can prevent the rear device from hampering the driver when the driver rides on the leaning vehicle.
Therefore, it is possible to obtain a configuration that allows for easy placement of the left foot on the left foot step and easy placement of the right foot on the right foot step in the leaning vehicle including the left front wheel and the right front wheel.
The rear device refers to, for example, components provided in a rear portion of the leaning vehicle, such as a license-plate-supporting bracket supporting a license plate, a reflector or a lighting device.
In another aspect, the leaning vehicle preferably includes the following configuration. The leaning vehicle further includes a rear-member-supporting part securing at least one of the rear fender or the rear device to the vehicle body frame.
Accordingly, at least one of the rear fender or the rear device can be supported to the vehicle body frame. Thus, a configuration with the rear fender and the rear device disposed in the rear portion of the leaning vehicle can be easily achieved.
In another aspect, the leaning vehicle preferably includes the following configuration. The upper end of the rear device is lower than an upper end of the rear fender.
This can prevent the rear device from having contact with the driver's foot and thereby hampering the driver, when the driver rides on the leaning vehicle.
In another aspect, the leaning vehicle preferably includes the following configuration. The rear device includes at least one of a license-plate-supporting bracket supporting a license plate, a reflector or a lighting device.
Accordingly, it is possible to obtain a configuration that allows the left foot to be easily placed on the left foot step and the right foot to be easily placed on the right foot step in the leaning vehicle where the license-plate-supporting bracket supporting the license plate, the reflector and the direction signal are disposed in the rear portion of the vehicle.
In another aspect, the leaning vehicle preferably includes the following configuration. The leaning vehicle further includes a lean suppressing mechanism switchable between an active state and an inactive state and being configured to suppress leftward or rightward leaning of the linkage mechanism in the active state and not to suppress the leftward or rightward leaning of the linkage mechanism in the inactive state. Accordingly, the driver can ride on the leaning vehicle in a state where the lean suppressing mechanism is in the active state, that is, leaning of the linkage mechanism is suppressed by the lean suppressing mechanism.

(Overall Configuration)
The leaning vehicle 1 does not include a seat on which a driver is seated. That is, the leaning vehicle 1 is a so-called standing-type vehicle which a standing driver drives while standing. The leaning vehicle 1 does not include a rear arm supporting the rear wheel 4. The rear wheel 4 of the leaning vehicle 1 is supported by a vehicle body frame 21 described later. The leaning vehicle 1 does not include buffer devices that elastically support the front wheels 3 and the rear wheel 4 such that the front wheels 3 and the rear wheel 4 are allowed to be displaced. The front wheels 3 and the rear wheel 4 of the leaning vehicle 1 are supported on the vehicle body frame 21 described later without interposition of buffer devices.
The vehicle body 2 includes the vehicle body frame 21 and a power unit 22. In
As illustrated in
The head pipe 211 is located in a front portion of the leaning vehicle 1. When the leaning vehicle 1 is seen from the left, an upper portion of the head pipe 211 is located further rearward than a lower portion of the head pipe 211 in the front-rear direction of the vehicle body frame 21. The linkage mechanism 5 is disposed around the head pipe 211. A steering shaft 652 described later is rotatably inserted in the head pipe 211.
The main frame 212 is connected to the head pipe 211. The main frame 212 is located further rearward than the head pipe 211 in the front-rear direction of the vehicle body frame 21. The main frame 212 supports the power unit 22. A rear end of the main frame 212 supports the rear wheel 4 such that the rear wheel 4 is rotatable about a wheel shaft 41. As illustrated in
As illustrated in
When the vehicle body frame 21 is seen from the left, the upper frame 213 extends rearward in the front-rear direction of the vehicle body frame 21 and downward in the top-bottom direction of the vehicle body frame 21 from the head pipe 211 toward the rear wheel 4. A rear end of the upper frame 213 is branched into two parts respectively located at the left and right of the rear wheel 4. Specifically, the upper frame 213 includes an upper-frame-left-rear end 213a located at the left of the rear wheel 4 and an upper-frame-right-rear end 213b located at the right of the rear wheel 4. The upper-frame-left-rear end 213a and the upper-frame-right-rear end 213b support the rear wheel 4 together with an under-frame-left-rear end 214c and an under-frame-right-rear end 214d described later. The power unit 22 is supported by the upper frame 213.
The under frame 214 includes an under-frame-front portion 214a and an under-frame-rear portion 214b. When the vehicle body frame 21 is seen from the left, the under-frame-front portion 214a extends from the head pipe 211 rearward in the front-rear direction of the vehicle body frame 21 and downward in the top-bottom direction of the vehicle body frame 21. A front end of the under-frame-front portion 214a is connected to the head pipe 211.
The under-frame-rear portion 214b extends rearward from a rear end of the under-frame-front portion 214a in the front-rear direction of the vehicle body frame 21. A rear end of the under-frame-rear portion 214b is branched into two parts respectively located at the left and right of the rear wheel 4. Specifically, the under-frame-rear portion 214b includes the under-frame-left-rear end 214c located at the left of the rear wheel 4 and the under-frame-right-rear end 214d located at the right of the rear wheel 4.
The under-frame-left-rear end 214c is connected to the upper-frame-left-rear end 213a. The connection between the under-frame-left-rear end 214c and the upper-frame-left-rear end 213a constitutes a main-frame-left-rear end 212a. The under-frame-right-rear end 214d is connected to the upper-frame-right-rear end 213b. The connection between the under-frame-right-rear end 214d and the upper-frame-right-rear end 213b constitutes a main-frame-right-rear end 212b. The main-frame-left-rear end 212a and the main-frame-right-rear end 212b support the rear wheel 4.
The main frame 212 includes the upper frame 213 and the under frame 214 described above so that strength and stiffness of the main frame 212 can be thereby enhanced. In a case where the height of the main frame in the top-bottom direction of the vehicle body frame is reduced, the main frame may include only the under frame.

As illustrated in
As illustrated in
A portion of the linkage mechanism 5 located at the left is a left portion. For example, the left portion includes the left side part 53. A portion of the linkage mechanism 5 located at the right is a right portion. For example, the right portion includes the right side part 54.
As in the linkage mechanism disclosed in International Patent Application Publication No. 2020/111254, also in the linkage mechanism 5 of this embodiment, the upper cross part 51, the lower cross part 52, the left side part 53, and the right side part 54 are supported by the vehicle body frame 21 such that the upper cross part 51 and the lower cross part 52 are kept in parallel with each other, and the left side part 53 and the right side part 54 are kept in parallel with each other.

The left suspension part 61 supports the left front wheel 31 to the linkage mechanism 5. The left suspension part 61 extends in the direction in which the intermediate steering axis Z extends. A lower end of the left suspension part 61 supports the left front wheel 31. An upper end of the left suspension part 61 is fixed to the left bracket 63.
The right suspension part 62 supports the right front wheel 32 to the linkage mechanism 5. The right suspension part 62 extends in the direction in which the intermediate steering axis Z extends. A lower end of the right suspension part 62 supports the right front wheel 32. An upper end of the right suspension part 62 is fixed to the right bracket 64.
The steering member 65 includes the handlebar 651 and the steering shaft 652.
The handlebar 651 is connected to an upper portion of the steering shaft 652. A part of the steering shaft 652 is rotatably supported by the head pipe 211. The steering shaft 652 rotates about the intermediate steering axis Z in accordance with an operation on the handlebar 651 by a driver.
An operation of the leaning vehicle 1 in which the leaning vehicle 1 leans leftward or rightward is similar to a lean operation disclosed in International Patent Application Publication No. 2020/111254. Thus, the operation in which the leaning vehicle 1 leans leftward or rightward will not be described in detail.
As illustrated in
The left-foot-load-transfer part 81 includes a left-foot-placing part 811 (left foot step) and a left coupling part 812. At least a part of the left-foot-placing part 811 is located rearward of the left front wheel 31.
The left-foot-placing part 811 includes a left-foot-placing face 811a on which the left foot of a standing driver is placed. The left coupling part 812 couples the left-foot-placing part 811 and the left side part 53 of the linkage mechanism 5 to each other. As illustrated in
As illustrated in
The right-foot-placing part 821 includes a right-foot-placing face 821a on which the right foot of a standing driver is placed. The right coupling part 822 couples the right-foot-placing part 821 and the right side part 54 of the linkage mechanism 5 to each other. The right coupling part 822 extends from the right side part 54 rearward in the front-rear direction of the vehicle body frame 21 and downward in the top-bottom direction of the vehicle body frame 21. A rear end of the right coupling part 822 is coupled to the right-foot-placing part 821. The right-foot-load-transfer part 82 is configured to be capable of transferring a load of the driver input through the right-foot-placing part 821, to the right side part 54. The right coupling part may be integrated with the right side part
With the configuration described above, a load applied to the left-foot-placing part 811 through the left foot of the driver and a load applied to the right-foot-placing part 821 through the right foot of the driver are individually adjusted to thereby control leaning of the vehicle body frame 21.
For example, as illustrated in
When a load is applied by a left foot to the left side part 53 through the left-foot-placing part 811, a force is exerted to the left side part 53 such that the left side part 53 is displaced in the downward direction of the vehicle body frame 21. Accordingly, leftward leaning of the vehicle body frame 21 can be suppressed in the left-right direction of the leaning vehicle 1.
On the other hand, when the vehicle body frame 21 leans to the right of the leaning vehicle 1, the right side part 54 is located further upward than the left side part 53 in the top-bottom direction of the vehicle body frame 21. When a load is applied by a right foot to the right side part 54 through the right-foot-placing part 821, a force is exerted to the right side part 54 such that the right side part 54 is displaced in the downward direction of the vehicle body frame 21. Accordingly, rightward leaning of the vehicle body frame 21 can be suppressed in the left-right direction of the leaning vehicle 1.
When the vehicle body frame 21 leans leftward or rightward from the upright state, the normal direction to the placing face of the left-foot-placing part 811 and the normal direction to the placing face of the right-foot-placing part 821 change. However, an angle formed by the direction in which the head pipe 211 extends (the direction in which the intermediate steering axis Z extends) and the placing face of the left-foot-placing part 811 and the placing face of the right-foot-placing part 821 does not change. That is, the normal direction to the placing face of the left-foot-placing part 811 and the normal direction to the placing face of the right-foot-placing part 821 constantly coincide with the top-bottom direction of the vehicle body frame 21.
The left-right-coupling member 83 couples the left-foot-placing part 811 and the right-foot-placing part 821 to each other in the left-right direction of the vehicle body frame 21 under the vehicle body frame 21. In the left-right direction of the vehicle body frame 21, a center portion of the left-right-coupling member 83 is supported by a rotation support part (not shown) fixed to a lower portion of the under frame 214 of the vehicle body frame 21, to be rotatable about the under frame 214. Accordingly, in the top-bottom direction of the vehicle body frame 21, the left-right-coupling member 83 leans in the top-bottom direction in accordance with upward or downward movement of the left-foot-placing part 811 and the right-foot-placing part 821.
In this manner, the left-foot-placing part 811 and the right-foot-placing part 821 move upward or downward in an interlocked manner in accordance with an input of a load from the left foot to the left-foot-placing part 811 or an input of a load from the right foot to the right-foot-placing part 821. Thus, with the input of a load from the left foot to the left-foot-placing part 811 or the input of a load from the right foot to the right-foot-placing part 821 described above, leftward or rightward leaning of the vehicle body frame 21 can be easily suppressed.
The lean suppressing mechanism 7 suppresses leftward or rightward leaning of the linkage mechanism 5. The lean suppressing mechanism 7 includes a lean suppressing operator 71, a lean-suppressing-brake disc 72, and an unillustrated caliper. The lean suppressing operator 71 is a lever-shaped member attached to the steering shaft 652. The lean-suppressing-brake disc 72 is a plate-shaped member in a U shape, and fixed to the left-right-coupling member 83. The caliper is fixed to the under frame 214 of the main frame 212. The caliper is configured to be capable of sandwiching the lean-suppressing-brake disc 72 in the thickness direction.
An operation to rotate the lean suppressing operator 71 triggers switching between an active state and an inactive state of the lean suppressing mechanism 7. When the lean suppressing mechanism 7 is activated, the caliper is driven and sandwiches the lean-suppressing-brake disc 72 in its thickness direction. This suppresses swinging of the left-right-coupling member 83 of the load transfer mechanism 8 with respect to the under frame 214 of the main frame 212. As described above, the left coupling part 812 of the load transfer mechanism 8 is coupled to the left side part 53 of the linkage mechanism 5, and the right coupling part 822 of the load transfer mechanism 8 is coupled to right side part 54 of the linkage mechanism 5. Thus, by activating the lean suppressing mechanism 7 with an operation of the lean suppressing operator 71, leftward or rightward leaning of the linkage mechanism 5 with respect to the main frame 212 can be suppressed.
The leaning vehicle 1 includes the lean suppressing mechanism 7 described above, so that the leaning vehicle 1 can suppress leftward or rightward leaning of the linkage mechanism 5 by the lean suppressing mechanism 7 when a driver rides on the leaning vehicle 1. Thus, the driver can easily place the left foot on the left-foot-placing part 811 and easily place the right foot on the right-foot-placing part 821.

(Rear Fender)
As illustrated in
The rear fender 42 is supported by the main frame 212 in each of a front portion and a rear portion. Specifically, the front portion of the rear fender 42 is fixed to the main frame cover 25 attached to the main frame 212 by a fastening member such as a bolt. The rear portion of the rear fender 42 is fixed to a rear-fender-left-supporting part 43 attached to the main-frame-left-rear end 212a, and to a rear-fender-right-supporting part 44 attached to the main-frame-right-rear end 212b.
The rear-fender-left-supporting part 43 and the rear-fender-right-supporting part 44 have higher support stiffness than a portion, in the rear fender 42, fixed to the main frame cover 25 attached to the main frame 212.
The rear-fender-left-supporting part 43 and the rear-fender-right-supporting part 44 correspond to a rear-member-supporting part 40 supporting the rear fender 42 to the vehicle body frame 21, and also correspond to a rear-fender-rear-supporting part 42b. In the rear fender 42, the portion which is fixed to the main frame cover 25 attached to the main frame 212 corresponds to a rear-fender-front-supporting part 42a.
Each of the rear-fender-left-supporting part 43 and the rear-fender-right-support portion 44 is a metallic plate-shaped member, and extends in a radial direction of the rear wheel 4. The rear-fender-left-supporting part 43 and the rear-fender-right-supporting part 44 extend in the top-bottom direction. The rear-fender-left-supporting part 43 is connected to the main-frame-left-rear end 212a and the rear fender 42 at the left of the rear wheel 4. That is, a lower end of the rear-fender-left-supporting part 43 is connected to the main-frame-left-rear end 212a. An upper end of the rear-fender-left-supporting part 43 is connected to a left portion of the rear fender 42. The rear-fender-right-supporting part 44 is connected to the main-frame-right-rear end 212b at the right of the rear wheel 4. That is, a lower end of the rear-fender-right-supporting part 44 is connected to the main-frame-right-rear end 212b. An upper end of the rear-fender-right-supporting part 44 is connected to a right portion of the rear fender 42.
A pair of rear-device-supporting parts 45 supporting rear device 100 described later are connected to the rear fender 42. The pair of rear-device-supporting parts 45 are metallic plate-shaped parts, and extend in a front-rear direction. Front portions of the pair of rear-device-supporting parts 45 are connected to a connecting portion between the rear fender 42 and the rear-fender-left-supporting part 43, and to a connecting portion between the rear fender 42 and the rear-fender-right-supporting part 44, respectively. That is, the pair of rear-device-supporting parts 45 are connected to the upper portions of the rear-fender-left-supporting part 43 and the rear-fender-right-supporting part 44. Accordingly, the pair of rear-device-supporting parts 45 can be supported by the rear-fender-left-supporting part 43 and the rear-fender-right-supporting part 44 with high stiffness. The pair of rear-device-supporting parts may be integrally formed.
As described later, the rear device 100 is fixed to rear portions of the pair of rear-device-supporting parts 45 by fastening members such as bolts.

The leaning vehicle 1 has the rear device 100 supported by rear ends of the vehicle body frame 21 and not including the rear fender 42. The rear device 100 is supported to the main frame 212 by the rear-fender-left-supporting part 43 and the rear-fender-right-supporting part 44. The rear device 100 includes, for example, a license-plate-supporting bracket 102, a reflector 101, and a lighting device 103.
The rear device 100 may include, for example, at least one of the license-plate-supporting bracket 102, the reflector 101 or the lighting device 103, or may include other components disposed in a rear portion of the leaning vehicle 1. The rear device 100 may include a plurality of components, or may include only a single component.
The reflector 101 includes, for example, a reflector reflecting light incident from the rear of the leaning vehicle 1, and a side reflector reflecting light incident from the left or the right of the leaning vehicle 1. In this embodiment, the reflector 101 is supported at a position further upward than a rotation center of the rear wheel 4 by the pair of rear-device-supporting parts 45. The reflector 101 is a flat plate member with a reflective material provided on the surface. The reflector 101 is attached to the pair of rear-device-supporting parts 45 such that the surface provided with the reflective material faces rearward.
The license-plate-supporting bracket 102 is, for example, a plate-shaped or frame-shaped member that supports a license plate. In this embodiment, the license-plate-supporting bracket 102 is located further upward than the wheel shaft 41 of the rear wheel 4, and supported by the pair of rear-device-supporting parts 45. In this embodiment, the reflector 101 is located further upward than the license-plate-supporting bracket 102.
The lighting device 103 is equipment capable of emitting light, such as a direction indicator, a taillight, a stop light or a license plate light. The lighting device 103 may include a laser drawing device projecting an image on a road surface behind the leaning vehicle 1.
In this embodiment, the lighting devices 103 are located at the left and the right of the reflector 101. The lighting devices 103 may be located further upward than the reflector 101 or may be located further downward than the reflector 101, in the top-bottom direction. The lighting devices 103 are also located further upward than the wheel shaft 41 of the rear wheel 4, and supported by the pair of rear-device-supporting parts 45.
The reflector 101 may be supported by the pair of rear-device-supporting parts 45 through another supporting member. The license-plate-supporting bracket 102 may be supported by the pair of rear-device-supporting parts 45 through another supporting member. The reflector 101 may be located at the same height as the wheel shaft 41 of the rear wheel 4 or may be located further downward than the wheel shaft 41 of the rear wheel 4, in the top-bottom direction. The license-plate-supporting bracket 102 may be located at the same height as the wheel shaft 41 of the rear wheel 4 or may be located further downward than the wheel shaft 41 of the rear wheel 4, in the top-bottom direction. The reflector 101 may be located further downward than the license-plate-supporting bracket 102. The lighting devices 103 may be located at the same height as the wheel shaft 41 of the rear wheel 4 or may be located further downward than the wheel shaft 41 of the rear wheel 4, in the top-bottom direction.

Accordingly, the rear device 100 can be disposed in the rear portion of the leaning vehicle 1 in such a manner to secure a space between the rear equipment 100 and each of the left-foot-placing part 811 and the right-foot-placing part 821 when the leaning vehicle 1 is seen in the left-right direction, at the left and the right of the rear wheel 4 of the leaning vehicle 1.
When a driver rides on the leaning vehicle 1, the driver rides on the leaning vehicle 1 from the rear. When the driver rides on the leaning vehicle 1 from the rear, the driver needs to place the feet at a left position and a right position of the rear wheel 4 of the leaning vehicle 1. Thus, it is necessary to secure spaces which allow the driver's feet to be placed therein at the left position and the right position of the rear wheel 4 of the leaning vehicle 1.
Therefore, by securing the space between the rear device 100 and each of the left-foot-placing part 811 and the right-foot-placing part 821 at the left and the right of the rear wheel 4 of the leaning vehicle 1, when the driver rides on the leaning vehicle 1 as described above, spaces S (see the crosshatched portions in
The half L1 of the length of the left-foot-placing part 811 in the front-rear direction may be equal to the half L3 of the length of the right-foot-placing part 821 in the front-rear direction, or may differ from the half L3 of the length of the right-foot-placing part 821 in the front-rear direction. The distance L2 in the front-rear direction from the rear end of the left-foot-placing part 811 to the front end of the rear device 100 may be equal to the distance L4 in the front-rear direction from the rear end of the right-foot-placing part 821 to the front end of the rear device 100, or may differ from the distance L4 in the front-rear direction from the rear end of the right-foot-placing part 821 to the front end of the rear device 100.
As illustrated in
Accordingly, when the driver rides on the leaning vehicle 1, the driver, with one of the feet placed on its corresponding one of the left-foot-placing face 811a or the right-foot-placing face 821a, can easily place the other foot on the other of the left-foot-placing face 811a or the right-foot-placing face 821a. Thus, when the driver rides on the leaning vehicle 1, the driver can easily place the left foot on the left-foot-placing face 811a and easily place the right foot on the right-foot-placing face 821a.
The upper end of the rear device 100 is located further downward than an upper end of the rear fender 42. This can prevent the rear device 100 from having contact with the driver's foot, when the driver rides on the leaning vehicle 1.
In this embodiment, the upper end of the rear device 100 refers to an upper end of a portion, in the rear device 100, located under an area which the driver's foot passes across when the driver rides on the leaning vehicle 1. In a case where the rear device 100 includes a plurality of components, the upper end of the rear device 100 refers to the highest end of portions, in the rear device 100, located under an area which the driver's foot passes across when the driver rides on the leaning vehicle 1.
The leaning vehicle 1 of this embodiment includes: the vehicle body frame 21; the left front wheel 31 disposed at the left of the vehicle body frame 21 in the left-right direction of the vehicle body frame 21; the right front wheel 32 disposed at the right of the vehicle body frame 21 in the left-right direction of the vehicle body frame 21; the rear wheel 4 located further rearward than the left front wheel 31 and the right front wheel 32 and rotatably supported by a rear portion of the vehicle body frame 21; the linkage mechanism 5 supported by a front portion of the vehicle body frame 21 and allowing the vehicle body frame 21 to lean leftward or rightward in the left-right direction of the vehicle body frame 21; the left-foot-placing part 811 which includes the left-foot-placing face 811a on which the left foot of a driver is placed, and is located between the left front wheel 31 and the rear wheel 4; and the right-foot-placing part 821 which includes the right-foot-placing face 821a on which the right foot of the driver is placed, and is located between the right front wheel 32 and the rear wheel 4. The leaning vehicle 1 further includes: the load transfer mechanism 8 capable of transferring a load to a left portion of the linkage mechanism 5 through the left-foot-placing part 811 and transferring a load to a right portion of the linkage mechanism 5 through the right-foot-placing part 821, or capable of transferring a load to the left portion of the linkage mechanism 5 through the right-foot-placing part 821 and transferring a load to the right portion of the linkage mechanism 5 through the left-foot-placing part 811; and the rear device 100 which is supported by the rear portion of the vehicle body frame 21 and does not include the rear fender covering at least a part of an upper portion of the rear wheel 4. The rear device 100 is located in the rear portion of the leaning vehicle 1 such that the distance L2 in the front-rear direction from the rear end of the left-foot-placing part 811 to the front end of the rear device 100 is greater than the half L1 of the length of the left-foot-placing part 811 in the front-rear direction, and the distance L4 in the front-rear direction from the rear end of the right-foot-placing part 821 to the front end of the rear device 100 is greater than the half L3 of the length of the right-foot-placing part 821 in the front-rear direction. The rear device 100 is located in the rear portion of the leaning vehicle 1 such that the height H1 of the upper end of the rear device 100 in the top-bottom direction from the left-foot-placing face 811a of the left-foot-placing part 811 is less than the height H2 of the left-foot-placing face 811a of the left-foot-placing part 811 in the top-bottom direction from the ground surface, and the height H3 of the upper end of the rear device 100 in the top-bottom direction from the right-foot-placing-face 821a of the right-foot-placing part 821 is less than the height H4 of the right-foot-placing face 821a of the right-foot-placing part 821 in the top-bottom direction from the ground surface. The rear device 100 is located between the center in the left-right direction of the left-foot-placing part 811 and the center in the left-right direction of the right-foot-placing part 821 when the leaning vehicle 1 is seen from the rear.
When a driver rides on the leaning vehicle 1 described above, the driver rides on the leaning vehicle 1 from the rear. When the driver rides on the leaning vehicle 1 from the rear, the driver needs to place the feet at the left position and the right position of the rear wheel 4 of the leaning vehicle 1. Thus, it is necessary to secure spaces which allow the driver's feet to be placed therein at the left position and the right position of the rear wheel of the leaning vehicle 1.
In the above-described configuration, therefore, the rear device 100 is located at a position apart in the front-rear direction from the left-foot-placing part 811 and the right-foot-placing part 821, as well as located between the center in the left-right direction of the left-foot-placing part 811 and the center in the left-right direction of the right-foot-placing part 821. Accordingly, the spaces S for the driver's feet to be placed therein can be secured at the left and the right of the rear wheel 4.
Furthermore, the height H1 of the upper end of the rear device 100 in the top-bottom direction from the left-foot-placing face 811a of the left-foot-placing part 811 is less than the height H2 of the left-foot-placing face 811a of the left-foot-placing part 811 in the top-bottom direction from the ground surface, and the height H3 of the upper end of the rear device 100 in the top-bottom direction from the right-foot-placing-face 821a of the right-foot-placing part 821 is less than the height H4 of the right-foot-placing face 821a of the right-foot-placing part 821 in the top-bottom direction from the ground surface. This can prevent the rear device 100 from hampering the driver when the driver rides on the leaning vehicle 1.
Therefore, it is possible to obtain a configuration that allows for easy placement of the left foot on the left-foot-placing part 811 of the load transfer mechanism 8 and easy placement of the right foot on the right-foot-placing part 821 of the load transfer mechanism 8 in the leaning vehicle 1 including the left front wheel 31 and the right wheel 32.
The leaning vehicle 1 of this embodiment further includes the rear-fender-left-supporting part 43 and the rear-fender-right-supporting part 44 which support at least one of the rear fender 42 or the rear device 100 to the vehicle body frame 21.
Accordingly, at least one of the rear fender 42 or the rear device 100 can be supported to the vehicle body frame 21. Thus, a configuration with the rear fender 42 and the rear device 100 disposed in the rear portion of the leaning vehicle 1 can be easily achieved.
In the leaning vehicle 1 of this embodiment, the upper end of the rear device 100 is lower than the upper end of the rear fender 42. This can prevent the rear device 100 from having contact with the driver's foot and thereby hampering the driver, when the driver rides on the leaning vehicle 1.
