This application is based on and claims priority under 35 U.S.C. ยง 119 to Japanese Patent Application 2017-156722, filed on Aug. 15, 2017, the entire content of which is incorporated herein by reference.
This disclosure generally relates to a handle apparatus for a vehicle.
A known handle apparatus disclosed in JP2003-41811A (which will be hereinafter referred to as Patent reference 1) is fixed to a vehicle door supported at a vehicle body so as to be relatively movable. The known handle apparatus includes a support member (frame) corresponding to a base member, and an outside handle (outer handle).
A vehicle outer-side surface of the vehicle door is formed of an outer panel. The support member is fixed to a vehicle inner-side surface of the outer panel. The support member is provided with an engaging portion (lock portion). The support member is also provided with a rotary support portion (support portion) and an adjacent space portion (an insertion port) which is adjacent to the rotary support portion.
Most part of the outside handle is positioned at the vehicle outer side relative to the outer panel. The outside handle includes a rotary shaft (engaging portion) and a pressing arm (insertion protrusion) extended towards a vehicle inner side. The rotary shaft is positioned at the vehicle inner side of the outer panel by passing through a through hole formed at the outer panel, and the rotary shaft is rotatably supported by the rotary support portion of the support member. Thus, the outside handle is rotatable about the rotary shaft between a first initial position and a first operation position, relative to the support member. The pressing arm is positioned at the vehicle inner side relative to the outer panel by passing through a through hole formed at the outer panel. A pressing portion is formed at a vehicle inner-side end portion (distal end portion) of the pressing arm.
A bell crank (handle lever) is supported by the support member to be rotatable about an axis extended in the horizontal direction and to be slidable in the horizontal direction (front-and-rear direction). The bell crank is rotatable between a second initial position (initial position) and a second operation position (operation position), relative to the support member. The bell crank is slidable between a no-hold portion and a temporary hold position, relative to the support member. The bell crank is biased by a bell crank biasing member to rotate towards the no-hold portion and towards the second initial position. The bell crank biasing member is provided between the bell crank and the support member. The bell crank includes a pressed portion and an engagement tab.
When the rotary shaft of the outside handle is rotatably supported by the rotary support portion of the support member and the pressing portion of the pressing arm is in contact (engages) with the pressed portion of the bell crank from the vehicle inner side, movement of the outside handle and movement of the bell crank are associated or linked with each other. That is, the bell crank is at the second initial position when the outside handle is positioned at the first initial position, and the bell crank is positioned at the second operation position when the outside handle is positioned at the first operation position.
The vehicle door is provided with a lock apparatus. The lock apparatus is connected to the bell crank via a linkage rod corresponding to a linkage member. Thus, when the outside handle is positioned at the first initial position and thus the bell crank is at the second initial position, the lock apparatus is in a latched state and restricts the vehicle door from performing an opening operation relative to the vehicle body. To the contrary, when the outside handle is positioned at the first operation position and thus the bell crank is at the second operation position, the lock apparatus is in an unlatched state and allows the vehicle door to perform the opening operation relative to the vehicle body.
To assemble the above-described known handle apparatus, first, an operator places the bell crank, which is integral with the support member separated from the outer panel, at an assembly position that is a predetermined rotational direction position between the second initial position and the second operation position with, for example, his or her hands against a biasing force of the bell crank biasing member. Further, the operator slides, against the biasing force of the bell crank biasing member, the bell crank to the temporary hold position. Thus, the engagement tab of the bell crank engages with the engaging portion of the support member. Accordingly, even if the operator releases his or her hand off the bell crank, a sliding direction position of the bell crank is kept at the temporary hold position and the rotational direction position of the bell crank is temporarily kept at the assembly position. At this time, the outside handle is positioned at a predetermined position between the first initial position and the first operation position.
Next, while the bell crank is maintained in the above-described state, the support member is fixed to the vehicle inner-side surface of the outer panel. The bell crank may be temporarily held at the temporary hold position and the assembly position after the support member is fixed to the vehicle inner-side surface of the outer panel.
Next, the rotary shaft and the pressing arm of the outside handle that is positioned at the vehicle outer side of the outer panel and is separated from the support member is made to pass through the through hole and be positioned at the vehicle inner side of the outer panel. Further, the rotary shaft is positioned in the adjacent space portion formed at the support member and the pressing portion of the pressing arm is made to come close to the pressed portion of the bell crank.
Subsequently, the pressing portion of the pressing arm is made to face the pressed portion of the bell crank from the vehicle inner side. When the bell crank and the outside handle are in the above-described positional relation, the outside handle can move relative to the support member (outer panel) so that the rotary shaft positioned in the adjacent space portion moves towards the rotary support portion. In other words, the rotary shaft of the outside handle comes to be movable towards the rotary support portion without the outside handle interfering with the bell crank. Thus, the rotary shaft of the outside handle is rotatably supported by the rotary support portion of the support member. Further, the pressing portion of the pressing arm is in contact with the pressed portion of the bell crank from the vehicle inner side.
When the rotational direction position of the bell crank is positioned at the second initial position, if the outside handle is made to move relative to the support member so that the rotary shaft positioned in the adjacent space portion moves towards the rotary support portion, the outside handle interferes with the bell crank. That is, the outside handle cannot move relative to the support member in such a manner that the rotary shaft is supported by the rotary support portion.
Then, the outside handle is made to rotate to the first operation position after the rotary shaft of the outside handle comes to be supported by the rotary support portion of the support member and the pressing portion of the pressing arm comes in contact with the pressed portion of the bell crank from the vehicle inner side. Thus, the pressing portion of the pressing arm that has moved towards the vehicle inner side presses the pressed portion of the bell crank towards the vehicle inner side, and accordingly the bell crank rotates from the assembly position to the second operation position. Thus, the engagement tab of the bell crank disengages from the engaging portion of the support member. Consequently, due to the biasing force of the bell crank biasing member, the sliding direction position of the bell crank shifts towards the no-hold portion and the rotational direction position becomes the second initial position.
The known outside handle is rotatably attached to the support member in the above-described procedures.
As is known, the lock apparatus includes a striker fixed to a vehicle body, a latch engaging with and disengaging from the striker and a pawl engaging with and disengaging from the latch. The lock apparatus further includes a latch biasing member biasing the latch such that the latch rotates in a direction in which the latch releases the striker and a pawl biasing member biasing the pawl such that the pawl rotates in a direction in which the pawl engages with the latch. Further, the linkage rod linked to the bell crank is connected to a pawl linkage member (open lever) serving as a component of the lock apparatus and linked to the pawl.
After completion of the attachment of the rotary shaft of the outside handle to the rotary support portion of the support member, when the outside handle positioned at the first initial position is rotated towards the first operation position, force is transmitted from the bell crank that has rotated towards the second operation position to the pawl linkage member via the linkage rod. Thus, a reaction force including the respective biasing forces of the latch biasing member and the pawl biasing member of the lock apparatus is transmitted from the linkage rod to the bell crank. The reaction force will be hereinafter referred to as a bell crank operation force.
When a positional relation of the lock apparatus and the handle apparatus to each other is in a predetermined positional relation, a direction of part of component force of the bell crank operation force may coincide with the moving direction of the bell crank from the no-hold position to the temporary hold position. Further, the component force may become larger than the biasing force with which the bell crank biasing member moves the bell crank towards the no-hold position. Thus, in such a case, the bell crank moves unintentionally to the temporary hold position due to the component force of the bell crank operation force. Consequently, when the operator releases his or her hand from the outside handle and accordingly the outside handle rotates from the first operation position towards the first initial position, the engagement tab of the bell crank unintentionally engages with the engagement portion of the support member when the bell crank has rotated from the second operation position to the assembly position. That is, the outside handle cannot be rotated to return to the first initial position (the bell crank cannot be rotated to return to the second initial position).
A need thus exists for a handle apparatus for a vehicle which is not susceptible to the drawback mentioned above.
According to an aspect of this disclosure, a handle apparatus for a vehicle includes a support member configured to be fixed to a vehicle door including a lock apparatus, and a bell crank supported by the support member to be rotatable between an initial position and an operation position. In a state where the bell crank is linked to the lock apparatus, the bell crank causes the lock apparatus to be in a latched state when the bell crank is in the initial position and causes the lock apparatus to be in an unlatched state when the bell crank is in the operation position. The latched state is configured to hold the vehicle door in a closed state and the unlatched state is configured to permit the vehicle door to open. The apparatus includes a handle including a pressing portion, and in a case where the handle is rotatably attached to the support member in a state where the pressing portion is in contact with a pressed portion provided at the bell crank, the handle causes, via the pressed portion and the pressing portion, the bell crank to rotate between the initial position and the operation position when the handle rotates. The apparatus includes a temporary hold member supported by the bell crank in such a manner that the temporary hold member is slidable between a first position and a second position and that the temporary hold member is biased to move to the first position, and the temporary hold member includes an engagement portion configured to engage with and disengage from an engaging portion provided at the support member when the temporary hold member is in the second position.
The foregoing and additional features and characteristics of this disclosure will become more apparent from the following detailed description considered with the reference to the accompanying drawings, wherein:
An embodiment disclosed here will be explained with reference to the drawings. The directions explained below correspond to the directions of the arrows shown in the drawings. A vehicle door 10 illustrated in
The configuration of the handle apparatus 20 will be described in detail. The handle apparatus 20 includes, as components thereof, a support member 21, a bell crank unit 30 and the outside handle 55.
The support member 21 made of hard resin or rigid resin is an integrally molded member that is extended in the front and rear direction as illustrated in
The bell crank unit 30 is attached to the bearing portions 27, 27 (bearing holes 28, 28), which are provided respectively at the front and the rear, of the support member 21 so as to be removable therefrom. For example, as illustrated in
The bell crank 31 includes a rotation center shaft 32 extended in the front and rear direction. A held portion 32a, of which a cross section is noncircular, is provided at each of a front end portion and a rear end portion of the rotation center shaft 32 (refer to
As illustrated in, for example,
An axis line of the compression coil spring 50 made of metal is extended in the front and rear direction. An inner diameter of the compression coil spring 50 is slightly larger than a diameter of the biasing member attachment portion 44 of the temporary hold portion 40 and is smaller than an outer diameter of the flange portion 41 of the temporary hold portion 40.
The bell crank 31, the temporary hold member 40 and the compression coil spring 50 are integrated with one another. To integrate the bell crank 31, the temporary hold member 40 and the compression coil spring 50 with one another, first, the main body portion 42 of the temporary hold member 40 is inserted into an inner space portion of the compression coil spring 50 from the rear side and the compression coil spring 50 is placed at an outer circumferential side of the biasing member attachment portion 44. As described above, the lower end of the tab portion 47 is positioned slightly at the inner circumferential side relative to the biasing member attachment portion 44 when the stopper 46 is in the free state, and the inner diameter of the compression coil spring 50 is larger than the diameter of the biasing member attachment portion 44. Accordingly, it is not highly likely that the tab portion 47 of the temporary hold portion 40 and the compression coil spring 50 interfere with each other when the main body portion 42 of the temporary hold member 40 is being inserted into the inner space portion of the compression coil spring 50. Thus, the temporary hold member 40 and the compression coil spring 50 can be assembled on each other easily.
Subsequently, the insertion portion 43 of the temporary hold member 40 that has been integrated with the compression coil spring 50 is inserted, from the rear side, into the support hole 37 of the support portion 36 of the bell crank 31. As described above, the lower end of the tab portion 47 is positioned at the outer circumferential side (lower side) relative to the flat surface 43a when the stopper 46 is in the free state. Accordingly, when the insertion portion 43 is being inserted into the support hole 37, the inclined surface 47b of the tab portion 47 comes in contact with a lower edge portion of a rear end portion of the support hole 37 and the stopper 46 becomes elastically deformed upwardly until the entire tab portion 47 is positioned inside the stopper accommodation hole 45. Thus, the tab portion 47 moves to the inside of the support hole 37. When the insertion portion 43 has been inserted into the support hole 37 by a certain amount of insertion, the tab portion 47 comes to face the stopper hole 38 of the support portion 36 of the bell crank 31 in a radial direction of the support hole 37. Then, the stopper 46 returns to be in the free state as illustrated in
Once the bell crank unit 30 is completed, the compression coil spring 50 is elastically deformed between a rear end surface of the support portion 36 and the flange portion 41 of the temporary hold member 40. In other words, the compression coil spring 50 becomes compressed from a free state, that is, compressed relative to the free state. Accordingly, the compression coil spring 50 exerts a biasing force which moves the temporary hold member 40 rearward relative to the support portion 36. The rearward movement of the temporary member 40 relative to the support 36 is restricted when the lock surface 47a of the tab portion 47 is in contact with the stopper surface 39 of the stopper hole 38 as illustrated in
A torsion coil spring 53, which is illustrated in for example
Once the rotation center shaft 32 has been placed by insertion in the bearing holes 28, the held portions 32a at the front and rear sides do not come off or fall off from the respective bearing holes 28 towards the vehicle inner side unless the held portions 32a are moved towards the vehicle inner side intentionally with a strong force. Further, a movement of the bell crank 31 in the front and rear direction relative to the support member 21 (the bearing portions 27 at the front and the rear) is restricted to a minute or very small range. More specifically, the movement of the bell crank 31 in the forward direction relative to the support member 21 is restricted at a position at which a front end surface of the shaft main body 32b is in contact with a rear surface of the bearing portion 27 which is arranged at the front side, and the movement of the bell crank 31 in the rear direction relative to the support member 21 is restricted at a position at which a rear end surface of the shaft main body 32b is in contact with a front surface of the bearing portion 27 which is arranged at the rear side. That is, the movement of the bell crank 31 in the front and rear direction relative to the support member 21 is allowed only in a range including a sum of dimensions resulting from adding a minute clearance between the front end surface of the shaft main body 32b and the rear surface of the bearing portion 27 at the front side, and a minute clearance between the rear end surface of the shaft main body 32b and the front surface of the bearing portion 27 at the rear side, to each other.
In a state where the torsion coil spring 53 is elastically deformed, one of lock portions provided at respective both end portions of the torsion coil spring 53 is locked at the bell crank 31 and the other of the lock portions, which are provided as a pair, is locked at the support member 21. Thus, when any other external forces in the rotational direction other than a rotational biasing force generated by the torsion coil spring 53 are not exerted on the bell crank 31, the bell crank unit 30 is rotationally biased in the clockwise direction in
Thus, when no other external force in the rotational direction other than the rotational biasing force of the torsion coil spring 53 is exerted on the bell crank 31 in a state where the temporary hold member 40 is positioned at the no-hold position, the counter weight 35 of the bell crank 31 is in contact with the front and rear temporary stopper surfaces 27a of the bearing portions 27, and accordingly the bell crank 31 is restricted from rotating (in the clockwise direction in
When an external force which is larger than the rotational biasing force of the torsion coil spring 53 and is in a direction opposite to the rotational biasing force of the torsion coil spring 53 is applied or exerted on the bell crank 31 when the bell crank 31 is positioned in the temporary initial position, the bell crank 31 rotates in the counter clock direction in
In a state where the relative rotational position of the bell crank unit 30 (bell crank 31) relative to the support member 21 is temporarily held at the assembly position, the bell crank unit 30 and the support member 21 are fixed to a vehicle inner-side surface of the outer panel 12 such that a vehicle outer-side surface of the support member 21 faces the assembly through holes 12a and 12b.
As illustrated in
The fixing portion 56 forms a front end portion of the outside handle 55. A vehicle outer-side surface of the fixing portion 56 is formed of a curved surface. A vehicle inner-side surface of the fixing portion 56 is fixed to the vehicle outer-side surface of the outer panel 12.
The handle main body 58 includes a grip portion 59, a rear insertion portion 61, a rotary shaft 62 and a pressing arm 64 in an integrated manner with one another. The grip portion 59 is extended in a substantially front and rear direction and a plane shape of the grip portion 59 is a substantially U-shape. A vehicle outer-side surface of the grip portion 59 is a curved surface. As illustrated in
The handle 58 is attached to the support member 21 from the vehicle outer-side of the outer panel 12 after the support member 21, which has been integrated with the bell crank unit 30 temporarily held at the assembly position, is fixed to the outer panel 12.
When attaching the handle main body 58 to the support member 21, first, the rear insertion portion 61 of the handle main body 58 is made to pass through the assembly through hole 12a and be positioned at the vehicle inner side of the outer panel 12, and the pressing arm 64 is made to pass through the assembly through hole 12b and be positioned at the vehicle inner side of the outer panel 12. Further, the rear insertion portion 61 and the rotary shaft 62 are placed by insertion in the adjacent space portion 22 of the support member 21. Further, as illustrated in FIG. 25, the pressing arm 64 is inserted into the arm through hole 26 of the support member 21. Then, inside the arm through hole 26, the pressing arm 64 is placed immediately in front of the input arm 33.
Subsequently, the pressing arm 64 is moved further towards the vehicle inner side relative to the support member 21 (outer panel 12), while the rear insertion portion 61 and the rotary shaft 62 being positioned in the adjacent space portion 22 of the support member 21. Thus, as illustrated in
If the bell crank 31 (bell crank unit 30) is presumed to be at the temporary initial position, the input arm 33 is positioned at the vehicle inner side relative to when the bell crank 31 is positioned at the assembly position as illustrated in
When the pressing portion 65 of the pressing arm 64 is in contact with the pressed portion 33a of the input arm 33 from the vehicle inside, the bell crank 31 and the outside handle 55 move in an associated manner or linked manner with each other. As illustrated in
In this state, when the operator releases his or her hand off the handle main body 58, the bell crank 31 is rotated by the rotational biasing force of the torsion coil spring 53 in the clockwise direction in
An upper end portion (front end portion) of a linkage rod 70 is rotatably connected to the rod connection hole 34 of the bell crank 31 of the handle apparatus 20 that has been mounted on the outer panel 12 in the above-described procedures. The linkage rod 70 is illustrated in
Next, operation of the lock apparatus 13 and the handle apparatus 20 which are attached to the vehicle door 10 will be explained.
As is well known, when the lock knob 14 is positioned at the lock position in a state where the vehicle door 10 closes the opening portion formed at the vehicle body, the lock apparatus 13 is in a latched state where the latch holds or grips a striker fixed to the vehicle body. In this case, when the outside handle 55 is rotated from the first initial position to the first operation position, the bell crank 31 positioned at the second initial position is rotated to the second operation position. Thus, the rotational force of the bell crank 31 is transmitted to the outside open lever of the lock apparatus 13 via the linkage rod 70, and accordingly the outside open lever rotates. In this case, however, the lock apparatus 13 remains in the latched state. To the contrary, in a state where the lock knob 14 is positioned at the unlock position, when the outside handle 55 is rotated from the first initial position to the first operation position, the outside open lever rotates and the rotational force of the outside open lever is transmitted to the latch via the open link and the pawl. As a result, the lock apparatus 13 is brought into an unlatch state in which the latch releases the striker. Consequently, the vehicle door 10 can be rotated in an open direction relative to the vehicle body.
When the outside handle 55 positioned at the first initial position is operated and rotated towards the first operation position and thus the bell crank 31 is rotated towards the second operation position relative to the assembly position, a bell crank operation force F corresponding to a predetermined force may be transmitted from the lock apparatus 13 to the bell crank 31 via the linkage rod 70 as illustrated in
As described above, when the temporary hold member 40 is positioned at the no-hold position, the positions, in the front and rear direction, of the engagement portion 48 of the temporary hold portion 40 and the engaging portion 29a of the support member 21 do not coincide with each other even if the forward component force of the bell crank operation force F is extended to the bell crank 31 during the rotational operation of the outside handle 55. That is, while the outside handle 55 is performing the rotational operation, the engagement portion 48 of the temporary hold portion 40 and the engaging portion 29a of the support member 21 do not engage with each other unintentionally, and thus the temporary hold member 40 does not come to be held at the temporary hold position unintentionally. Consequently, when the outside handle 55 is rotated towards the first initial position after the outside handle 55 positioned at the first initial position is rotated to the first operation position, the outside handle 55 rotates and returns to the first initial position reliably and the bell crank 31 rotates and returns to the second initial position reliably.
The disclosure is not limited to the above-described embodiment.
For example, an inside handle (operation member) may be rotatably provided at a trim of the vehicle door 10. The inside handle is linked to an inside open lever via an operation wire, for example. The inside open lever is positioned at an initial position when the inside handle is positioned at an initial position, and the inside open lever does not exert any force on the outside open lever of the lock apparatus 13. The inside open lever does not exert any forces or does not influence the outside open lever of the lock apparatus 13. On the other hand, when the inside handle moves from the initial position to a latch-released position, the inside open lever moves to a latch-released position and causes the outside open lever of the lock apparatus 13 to move to a latch-released position.
This disclosure is applicable to a handle apparatus configured to be provided at a swing-type vehicle door.
An objective of this disclosure is to provide a handle apparatus for a vehicle which can prevent a bell crank from being temporarily held at an assembly position unintentionally when a handle is operated.
According to the aforementioned embodiment, the handle apparatus for a vehicle includes the support member 21 configured to be fixed to the vehicle door 10 including the lock apparatus 13. The apparatus includes the bell crank 31 supported by the support member 21 to be rotatable between the second initial position and the second operation position. In a state where the bell crank 31 is linked to the lock apparatus 13, the bell crank 31 causes the lock apparatus 13 to be in the latched state when the bell crank 31 is in the second initial position and causes the lock apparatus 13 to be in the unlatched state when the bell crank 31 is in the second operation position. The latched state is configured to hold the vehicle door 10 in the closed state and the unlatched state is configured to permit the vehicle door 10 to open. The apparatus includes the handle 55 including the pressing portion 65. In a case where the handle 55 is rotatably attached to the support member 21 in a state where the pressing portion 65 is in contact with the pressed portion 33a provided at the bell crank 31, the handle 55 causes, via the pressed portion 33a and the pressing portion 65, the bell crank 31 to rotate between the initial position and the operation position when the handle 55 rotates. The apparatus includes the temporary hold member 40 supported by the bell crank 31 in such a manner that the temporary hold member 40 is slidable between the no-hold position (i.e., the first position) and the temporary hold position (i.e., the second position) and that the temporary hold member 40 is biased to move to the no-hold position. The temporary hold member 40 includes the engagement portion 48 configured to engage with and disengage from the engaging portion 29a provided at the support member 21 when the temporary hold member 40 is in the temporary hold position.
According to the above-described configuration, only when the temporary hold member 40 is at the temporary hold position and the bell crank 31 is at the predetermined assembly position between the second initial position and the second operation position, the engagement portion 48 of the temporary hold member 40 engages with the engaging portion 29a of the support member 21 thereby to temporarily hold the bell crank 31 at the assembly position. When the bell crank 31 is at the assembly position, the handle 55 is attachable to the support member 21 in such a manner that the pressing portion 65 is in contact with the pressed portion 33a of the bell crank 31. Further, when the handle is rotated towards the second operation position after the attaching operation of the handle 55 to the support member 21 is completed, the engagement portion 48 of the temporary hold member 40 becomes separated from the engaging portion 29a of the support member 21. Accordingly, the temporary member 40 that has been biased towards the no-hold position moves to the no-hold position automatically.
When the bell crank 31 positioned at the second initial position is rotated towards the second operation position relative to the assembly position by performing the rotational operation on the handle 55, the bell crank operation force F, which is the predetermined force, might be transmitted from the lock apparatus 13 to the bell crank 31. The temporary hold member 40 of the disclosure, however, is configured to slide relative to the bell crank 31 between the no-hold position and the temporary hold position. Thus, the bell crank operation force F does not act between the temporary hold member 40 and the bell crank 31. Further, the temporary hold member 40 is biased to move to the no-hold position relative to the bell crank 31. Accordingly, the temporary hold member 40 is not moved, by the bell crank operation force F that has been transmitted to the bell crank 31, from the no-hold position relative to the bell crank 31. Consequently, thereafter, when the handle 55 is operated to rotate in the direction which causes the bell crank 31 to rotate to the second initial position, the bell crank 31 rotates to the second initial position reliably.
According to the aforementioned embodiment, the range in which the bell crank 31 is configured to move relative to the support member 21 in the direction that is parallel with the sliding direction of the temporary hold member 40 is limited to the range in which the engagement portion 48 of the temporary hold member 40 positioned in the first position is unable to engage with the engaging portion 29a.
According to the above-described configuration, even in a case where the bell crank 31 is movable relative to the support member 21 in the direction that is parallel with the sliding direction of the temporary hold member 40, when the temporary hold member 40 is positioned at the no-hold position, the engagement portion 48 of the temporary hold member 40 and the engaging portion 29a of the support member 21 do not engage with each other regardless of the rotational direction position of the bell crank 31. Consequently, after the engagement portion 48 of the temporary hold member 40 has disengaged from the engaging portion 29a of the support member 21, when the handle 55 is operated to rotate in the direction which causes the bell crank 31 to rotate to the second initial position, the bell crank 31 rotates to the second initial position more reliably.
According to the aforementioned embodiment, the bell crank 31 includes the support portion 36 supporting the temporary hold member 40 in a manner that the temporary hold member 40 is slidable. The compression coil spring 50 (i.e., the biasing member) is provided between the support portion 36 and the temporary hold member 40, the compression coil spring 50 biasing the temporary hold member 40 such that the temporary hold member 40 moves to the first position. The temporary hold member 40 includes the stopper 46 engaging with the support portion 36 when the temporary hold member 40 is positioned at the first position and restricting the temporary hold member 40 from moving towards the side opposite to the second position.
According to the above-described embodiment, with the simple structure, the temporary hold member 40 positioned at the no-hold position can be restricted from moving to the side opposite to the temporary hold position.
According to the aforementioned embodiment, the support portion 36 includes the cylindrical body extended in the direction which is parallel with the sliding direction of the temporary hold member 40 and provided with the stopper hole 38 formed at the inner circumferential surface of the cylindrical body. The temporary hold member 40 is placed by insertion in the inside space portion of the support portion 36 to be slidable, and the stopper 46 is slidably positioned in the stopper hole 38 and is in contact with the stopper surface 39 corresponding to the portion of the inner surface of the stopper hole 38, such that the stopper 46 restricts the temporary hold member 40 from moving towards a side opposite to the second position.
According to the above-described embodiment, with the simple structure, the temporary hold member 40 positioned at the no-hold position can be restricted from moving to the side opposite to the temporary hold position.
According to the aforementioned embodiment, the biasing member corresponds to the compression coil spring 50 of which the axial direction is extended to be parallel with the sliding direction of the temporary hold member 40, and the compression coil spring 50 is held in a state in which the compression coil spring 50 is compressed between the support portion 36 and the temporary hold member 40 compared to the free state. The temporary hold member 40 includes the biasing member attachment portion 44 corresponding to the annular surface, the compression coil spring 50 is arranged at the outer circumferential side of the biasing member attachment portion 44, the position of the biasing member attachment portion 44 in the axial direction is different from the position of the stopper 46 in the axial direction, and the stopper 46 is positioned at the inner circumferential side of the biasing member attachment portion 44 when the temporary hold member 40 is viewed in the axial direction.
According to the above-described configuration, when the compression coil spring 50 is being attached to the temporary hold member 40 so as to be arranged at the outer circumferential side of the biasing member attachment portion 44, a possibility that the compression coil spring 50 interferes with the stopper 46 can be reduced. In other words, the compression coil spring 50 is attached to the temporary hold member 40 easily.
