Only the right blinker device 50RR is shown.) are attached. The front and rear blinker devices 50 can be structured in common.
Referring to
On the inner side in the vehicle width direction of the blinker housing 51, an elastic member 60 to elastically support the blinker device 50 on the side of a vehicle body is provided. The elastic member 60 made of rubber or the like is fitted to a fixing portion on the side of a vehicle body (hereinafter, may be simply referred to as a fixing portion) 24a consisting of an opening formed in the tabular rear fender 24. The elastic member 60 includes a main body portion 61 exposed to the outside of the vehicle body, a small-diameter portion 63 that is fitted to the fixing portion 24a, and a flange portion 62 having a cross-sectional area larger than that of the small-diameter portion 63. The opening of the fixing portion 24a is formed to have substantially the same shape as that of the small diameter portion 63.
To fit the elastic member 60 to the fixing portion 24a on the side of a vehicle body, the flange portion 62 being a part of the elastic member 60 is temporarily elastically deformed and inserted through the fixing portion (opening) 24a. Accordingly, the small-diameter portion 63 is housed inside the fixing portion 24a, and positioning of the elastic member 60 is completed.
Then, when the tabular fixing member 80 in contact with the flange portion 62 is fixed to a predetermined position by screwing a bolt 90 as a fastening member, the blinker housing 51, the elastic member 60, and the fixing member 80 are integrally fixed. In addition, the flange portion 62 is prevented from deforming by proximal disposition of the main body portion 81 of the fixing member 80, and accordingly, the elastic member 60 is prevented from coming out of the fixing portion 24a.
Between the fastening member 90 and the fixing member 80, a washer 91 is provided. On a lower portion of the fixing member 80, a wiring guide portion 82 for forming a passage 82a of wirings 92 (refer to
The blinker device 50 is mounted on the side of a vehicle body in such a manner that after the elastic member 60 is fitted to the fixing portion 24a on the side of the vehicle body, into the opening portion of the blinker housing 51, the elastic member 60 is inserted, and the fixing member 80 is inserted from the inside of the vehicle body, and then the fastening member 90 is screwed via the washer 91.
In the opening portion of the blinker housing 51, a cylindrical boss 57 in which an insert nut 58 is embedded is provided. On the side surface of the boss 57, a tabular positioning projection 59 that is stood on a radially outer side of the boss 57 is provided. On the vehicle body front side of the boss 57, an engagement hole 77 is formed by tabular ribs 75 and 76 that are provided substantially symmetrically in the vertical direction. On the other hand, on the elastic member 60 side, an engagement projection 66 that is engaged in the engagement hole 77 and a waterproof rib 67 disposed so as to surround an area from the upper side to the lateral lower side of the boss 57, are provided.
In the elastic member 60, a through hole 64 for wiring through which the wirings 92 are inserted, and a through hole 65 for a fastening member through which the fastening member 90 is inserted, are formed. On the other hand, as described above, in the main body portion 81 of the fixing member 80, the wiring hole portion 83 having the cut-away 83a and the circular fastening hole portion 86 are formed. The main body portion 81 of the fixing member 80 is provided with a halved cylindrical portion 84 that is stood from a rim of the wiring hole portion 83, and a tubular collar member 85 that is parallel to the halved cylindrical portion 84 and stood from a rim of the fastening hole portion 86.
When fitting the fixing member 80 to the elastic member 60, the halved cylindrical portion 84 is inserted in the through hole 64 for wiring and the collar member 85 is inserted in the through hole 65 for a fastening member. The halved cylindrical portion 84 and the collar member 85 both have a function to increase the rigidity of the blinker mounting base portion.
Here, assembling of the blinker device 50 according to the present embodiment is performed on the condition that the wirings 92 are inserted in the through hole 64 for wiring of the elastic member 60 in advance, before the fixing member 80 is inserted in the elastic member 60. This is because even when a component such as a connector 94 or the like is attached to the tip end of the wiring 92, the wiring can be easily inserted when the through hole for wiring is in a state where the cross-sectional area of thereof is large before the halved cylindrical portion 84 is inserted. In other words, the through hole 64 for wiring can be reduced in diameter to a size that is just enough for the connector 94 to pass through. Since the wiring hole portion 83 of the fixing member 80 is provided with the cut-away 83a, the wirings 92 can be housed in substantially the center of the wiring hole portion 83 in a state where the elastic member 60 and the fixing member 80 are engaged with each other.
With the above-described arrangement, even when both of the hole through which the fastening member 90 is inserted and the hole through which the wirings 92 are inserted are provided, the through hole 64 for wiring of the elastic member 60 and the wiring hole portion 83 of the fixing member 80 can be prevented from increasing in diameter, and the mounting base portion of the blinker device 50 can be downsized.
In the present embodiment, the hole through which the fastening member 90 is inserted and the hole through which the wirings 92 are inserted are disposed side by side to each other in the vehicle body front-rear direction, therefore, the dimension in the vertical direction of the mounting base portion of the blinker device 50 can be reduced, and the mounting base portion can be made to look slim in a front view or rear view of the blinker device 50, and the air resistance during traveling can be reduced.
Referring to
With the positioning structure using the positioning projection 59 of the boss 57, the positioning structure using the engagement projection 66, and the positioning structure using the waterproof rib 67 described above, the possibility of erroneous fitting that causes, for example, the drainage hole 70 to be positioned at the upper side, can be reduced.
The substrate 53 on which two light sources 54 are mounted is fixed to a standing portion 56 formed on the blinker housing 51 by a screw 55, and the wirings 92 are connected to the back surface side of the substrate 53. The wiring guide portion 82 also has a function to, even when the wirings 92 are externally pulled when mounting or removing the blinker device 50, etc., receive this pulling force and prevent it from influencing the portion connected to the substrate 53.
The boss 57 of the blinker housing 51 projects from an end portion of an outer shell member of the blinker housing 51 to the elastic member 60 side, and when the fastening member 90 is fastened via the fixing member 80, the collar member 85 of the fixing member 80 comes into contact with an end face of the boss 57, and the three components are fixed to each other without space between them.
The halved cylindrical portion 84 of the fixing member 80 is inserted in the blinker housing 51 side to a depth equivalent to the depths of the tip end portion of the screwed fastening member 90 and the engagement projection 66 of the elastic member 60. Accordingly, the distance of guiding the wirings 92 by a metal plate becomes longer, and smooth routing is possible.
As a positioning structure between the blinker housing 51 and the elastic member 60, both of a portion projecting from the blinker housing 51 side similar to the positioning projection 59 and a portion projecting from the elastic member 60 side similar to the engagement projection 66 are applied, and by providing these portions respectively projecting to each other from the blinker housing and the elastic member, reliable positioning is enabled.
In the present embodiment, since setting is performed so that the halved cylindrical portion 84 does not pass through the through hole 65 for a fastening member by making the diameter D2 of the through hole 64 for wiring larger than the diameter D1 of the through hole 65 for a fastening member of the elastic member 60, erroneous fitting hardly occurs as well when the fixing member 80 is fitted to the elastic member 60.
The structure of the blinker device and the shapes and materials of the fixing portion on the side of a vehicle body, the blinker housing, the elastic member, and the fixing member, and the shapes, etc., of the boss of the blinker housing, the positioning projection of the elastic member, the halved cylindrical portion of the fixing member and the collar member, are not limited to those of the above-described embodiment, and can be variously changed. For example, it is also possible to arrange the hole through which the wirings are inserted and the hole through which the fastening member is inserted in the vehicle body vertical direction. The blinker device according to the present invention is applicable to various vehicles such as a saddle-type three-wheeled vehicle/four-wheeled vehicle as well as a motorcycle.
