Detailed Description

Hereinafter, an embodiment of a pedal device for a vehicle will be described with reference to the drawings.

As shown in fig. 1, the vehicle 1 includes a slide door 4. The slide door 4 can open and close the door opening 3 provided on the side surface of the vehicle body 2 by moving in the vehicle front-rear direction. The vehicle front-rear direction corresponds to the left-right direction of fig. 2.

Specifically, as shown in fig. 2, in the vehicle 1, a plurality of guide rails 10 extending in the vehicle front-rear direction are provided on the side surface of the vehicle body 2. Specifically, the guide rail 10 includes: a lower rail 11 disposed at a lower edge of the door opening 3; a center rail 12 disposed behind the door opening 3; and an upper rail 13 disposed at an upper edge portion of the door opening portion 3. Further, a guide roller unit 20 is coupled to each guide rail 10. Each guide roller unit 20 is movable along the extending direction of each guide rail 10. In the vehicle 1, the slide door 4 is supported by the vehicle body 2 via the guide roller units 20. This enables the slide door 4 to open and close along each guide rail 10 extending in the vehicle front-rear direction. That is, the moving path of the slide door 4 extends in the vehicle front-rear direction.

As shown in fig. 3A and 3B, each guide rail 10 has a curved portion 30 at a longitudinal end 10f on the vehicle front side, and the curved portion 30 is curved inward in the vehicle width direction (upward in fig. 3) from the vehicle rear side toward the front side. In a state where each guide roller unit 20 is positioned at the longitudinal end 10f of each guide rail 10, the slide door 4 is in a completely closed state. For convenience of explanation, fig. 3A shows the lower-stage track 11 and the lower-stage roller unit 21, fig. 3B shows the center track 12 and the center roller unit 22, and the illustration of the upper-stage track 13 and the upper-stage roller unit 23 is omitted. When guided by the curved portion 30 provided in each guide rail 10, the slide door 4 is opened and closed in the vehicle front-rear direction along with displacement in the vehicle width direction.

The slide door 4 is constituted by: with the slide door 4 in the fully closed position Pc, the outer surface 4a thereof is substantially aligned with the side surface 2a of the vehicle body 2. When the opening operation is performed from the fully closed position Pc, the slide door 4 moves toward the vehicle rear side while moving toward the vehicle width direction outer side. That is, the width direction shift section Rc in which the slide door 4 is shifted in the vehicle width direction is located on the side where the fully closed position Pc exists on the movement path R of the slide door 4. In fig. 3, the slide door 4 that opens and closes is shown by a one-dot chain line, and more specifically, the trajectory of the tip end portion thereof. The vehicle 1 is thus configured such that the slide door 4 that performs the opening and closing operation does not interfere with the vehicle body 2.

As shown in fig. 2, the vehicle 1 is provided with an electric sliding door device 31 for opening and closing the sliding door 4 using a motor 31m as a driving source. Thus, the vehicle 1 is not limited to manual operation by the occupant, and the slide door 4 can be opened and closed by a door handle, an operation switch provided in the vehicle interior, or the like, not shown, or by operation of a portable device.

As shown in fig. 1 and 2, the vehicle 1 is provided with a pedal device 41 for use by an occupant when the vehicle 1 is ascending or descending. The pedal device 41 deploys a pedal member 40 as a pedal below the door opening 3.

Specifically, as shown in fig. 4A, 4B, 5A, 5B, and 6, the pedal device 41 includes: a movable pedal 42 supported below the door opening 3 in a movable state in the vehicle width direction; and an assist pedal 43 disposed below the door opening 3 together with the movable pedal 42 in a state of being fixed to the vehicle body 2. In fig. 4A, 4B, 5A, and 5B, the vertical direction is the vehicle width direction, and in fig. 6, the horizontal direction is the vehicle width direction. In the pedal device 41, the assist pedal 43 is provided above the movable pedal 42. Specifically, the assist pedal 43 includes a base portion 45 fixed to the side surface 2a of the vehicle body 2 and a pedal portion 46 connected to the base portion 45 so as to be rotatable. The pedal portion 46 is displaced in the vertical direction by rotation about its coupling shaft 46 x. The assist pedal 43 is configured to be in contact with the upper surface 42a of the movable pedal 42 disposed below the assist pedal 43 by the pedal portion 46 being displaced in the vertical direction.

As shown in fig. 5A, 5B, 6, and 7, the pedal device 41 includes a plurality of support arms 47, and each support arm 47 is rotatably coupled to the vehicle body 2 and to the movable pedal 42. In the pedal apparatus 41, each support arm 47 is coupled to the vehicle body 2 via a plurality of support brackets 48 fixed to the lower surface 2b of the vehicle body 2. Each support arm 47 pivots about the 1 st pivot coupling point M1 as a fulcrum with respect to each support bracket 48, and pivots about the 2 nd pivot coupling point M2 as a fulcrum with respect to the movable pedal 42. Thus, the movable pedal 42 supported by the support arm 47 moves in the vehicle width direction below the assist pedal 43 while maintaining a substantially horizontal posture.

The support arm 47 includes two main arms 51 disposed apart in the vehicle front-rear direction, and an auxiliary arm 52 disposed between these two main arms 51. The assist arm 52 is formed by rotatably coupling a base end-side arm 53 coupled to the vehicle body 2 and a tip end-side arm 54 coupled to the movable pedal 42. That is, the auxiliary arm 52 has a bendable joint M3. The support bracket 48 includes a front bracket 48f that couples the front main arm 51f and the sub-arm 52 to the vehicle body 2, and a rear bracket 48r that couples the rear main arm 51r to the vehicle body 2.

As shown in fig. 4A, 4B, 5A, 5B, and 6, the movable pedal 42 is moved outward in the vehicle width direction below the assist pedal 43, and is thereby disposed at a deployed position P2 that protrudes outward in the vehicle width direction from the assist pedal 43. Further, the assist pedal 43 maintains the state in which the pedal portion 46 abuts against the upper surface 42a of the movable pedal 42 even when the movable pedal 42 is in the deployed position P2. The design surface 46S of the pedal portion 46 forms a pedal surface S2 that is integral with the pedal surface S1 of the movable pedal 42.

As shown in fig. 4A, 4B, 6, and 7, the movable pedal 42 includes a movable base 55 having a substantially flat plate-like outer shape, and a resin cover 56 covering an upper portion of the movable base 55. The base portion 45 and the step portion 46 of the assist step 43 are also formed by laminating a resin cover 58 on a base member 57 having a substantially flat plate-like outer shape. The resin cover 58 constitutes the design surfaces 45s, 46s of the base portion 45 and the step portion 46, respectively. Thus, the resin cover 56 of the movable pedal 42 and the resin cover 58 covering the pedal portion 46 of the assist pedal 43 form the pedal surfaces S1 and S2, respectively.

As shown in fig. 4A to 8, the pedal device 41 includes a guide rail 60, and is provided on the lower surface 42b of the movable pedal 42 so as to extend along the longitudinal direction of the movable pedal 42 extending in the vehicle longitudinal direction.

As shown in fig. 7 and 8, the guide rail 60 includes a pair of side wall portions 61, 62 facing each other in the vehicle width direction. The guide rail 60 includes a retaining flange 63, and the retaining flange 63 extends from the side wall portion 62 located on the vehicle width direction inner side to the side wall portion 61 located on the vehicle width direction outer side. The retaining flange 63 is formed by bending a lower end portion of the side wall portion 62. The pedal device 41 includes a guide roller unit 70, and the guide roller unit 70 includes a guide roller 65 disposed between the two side wall portions 61, 62 of the guide rail 60. The guide roller unit 70 is supported by the slide door 4.

The guide roller unit 70 moves integrally with the slide door 4 in accordance with the opening and closing operation of the slide door 4. Thereby, the guide roller 65 disposed in the guide rail 60 also moves in the vehicle front-rear direction in accordance with the operation direction of the slide door 4. The guide rail 60 prevents the guide roller 65 disposed between the two side wall portions 61 and 62 from coming off by the retaining flange 63 provided at the lower end of the side wall portion 62. The guide roller unit 70 is configured as follows: the movable step 42 provided with the guide rail 60 is moved in the vehicle width direction by the guide rollers 65 pressing the side wall portion 61 of the guide rail 60 positioned on the outer side in the vehicle width direction or the side wall portion 62 of the guide rail 60 positioned on the inner side in the vehicle width direction while rubbing against the both side walls.

Specifically, the guide roller 65 abuts against the side wall portion 61 of the guide rail 60 located on the outer side in the vehicle width direction, and moves toward the vehicle rear side, which is the opening operation direction of the slide door 4, in the guide rail 60 while pressing the side wall portion 61. Thereby, the guide roller unit 70 moves the movable pedal 42 outward in the vehicle width direction. The guide roller 65 abuts against the side wall portion 62 of the guide rail 60 located on the vehicle width direction inner side, presses the side wall portion 62, and moves to the vehicle front side as the closing operation direction of the slide door 4 in the guide rail 60. Thereby, the guide roller unit 70 moves the movable pedal 42 inward in the vehicle width direction. The pedal device 41 is formed as follows: the movable pedal 42 moves from the retracted position P1 to the deployed position P2 in conjunction with the opening operation of the slide door 4, and the movable pedal 42 moves from the deployed position P2 to the retracted position P1 in conjunction with the closing operation of the slide door 4 (see fig. 4A to 5B).

As shown in fig. 4A to 5B and fig. 7, the guide rail 60 includes a curved portion 60c that curves from the vehicle rear side toward the front side toward the vehicle width direction inner side at the longitudinal direction end 60f on the vehicle front side, similarly to the curved portion 30 described above of each guide rail 10 provided to the slide door 4. In a state where the guide roller unit 70 is positioned at the longitudinal end 60f of the guide rail 60, the slide door 4 is in a completely closed state. The pedal device 41 can move the movable pedal 42 in the vehicle width direction stably by smoothly moving the guide roller 65 in the guide rail 60 in accordance with the opening and closing operation of the slide door 4.

More specifically, as shown in fig. 9, 10A, 10B, and 11, the guide roller unit 70 includes: a fixing member 71 fixed to the slide door 4 in a state of extending in the vertical direction; and an arm member 72 rotatably coupled to a lower end of the fixing member 71. In the guide roller unit 70, the arm member 72 is coupled to the fixed member 71 via a shaft-like member 73 serving as a rotation shaft thereof. Thus, the tip side of the arm member 72 extends inward in the vehicle width direction. A support shaft 65x extending in the vertical direction is provided at the distal end of the arm member 72. The guide roller unit 70 is configured to rotatably support the guide roller 65 via a support shaft 65 x.

The guide roller unit 70 includes a torsion spring 75, and the torsion spring 75 is interposed between the fixed member 71 and the arm member 72 in a state of being fitted to the outer periphery of the shaft-like member 73. In a state where the fixing member 71 is fixed to the sliding door 4, an urging force in a direction in which the guide roller 65 supported at the distal end of the arm member 72 is lifted upward is applied to the arm member 72 by an elastic force of the torsion spring 75 as an urging member.

That is, in a coupled state in which the guide roller 65 is coupled to the guide rail 60 provided in the movable pedal 42, the guide roller 65 is supported in the guide rail 60 so as to lift the distal end side of the arm member 72 upward in accordance with the biasing force of the torsion spring 75 (see fig. 10A). In the non-coupled state in which the guide roller 65 is disengaged from the guide rail 60, the arm member 72 is further rotated so as to bring the distal end side of the support guide roller 65 closer to the upper end portion of the fixing member 71 in accordance with the urging force of the torsion spring 75 (see fig. 10B). By compactly folding the guide roller unit 70, the workability in the non-coupled state is improved, and the guide roller unit 70 does not become an obstacle to the occupant using the slide door 4.

Specifically, as shown in fig. 7 and 11, the guide rail 60 has a notch 77, and the notch 77 is formed by cutting a part of the retaining flange 63 provided at the lower end of the side wall 62. More specifically, the guide rail 60 includes a plurality of notch portions 77 provided at positions on the vehicle rear side of the curved portion 60 c. Further, the pedal device 41 can insert the guide roller 65 of the guide roller unit 70 supported by the slide door 4 into the guide rail 60 provided on the lower surface 42b side of the movable pedal 42 and can separate the guide roller 65 from the guide rail 60 by the notch 77.

That is, as shown in fig. 11, the guide rail 60 allows the guide roller 65, which passes over the retaining flange 63 provided at the lower end of the side wall portion 62, to move in the vertical direction at the longitudinal position provided at the notch portion 77. The guide roller unit 70 pushes down the arm member 72, and the arm member 72 can be rotated against the urging force of the torsion spring 75. The guide roller unit 70 releases the pressing force, and thereby can rotate the arm member 72 again in accordance with the urging force of the torsion spring 75.

That is, the pedal device 41 can insert the guide roller 65 provided at the tip end of the arm member 72 into the guide rail 60 from below by rotating the arm member 72 based on the biasing force of the torsion spring 75 by using the notch 77 provided in the guide rail 60. Further, the arm member 72 is rotated against the urging force of the torsion spring 75, whereby the guide roller 65 supported in the guide rail 60 can be disengaged below the guide rail 60. Thus, the pedal device 41 easily connects and disconnects the slide door 4 supporting the guide roller unit 70 to and from the movable pedal 42 provided with the guide rail 60.

As shown in fig. 12 to 14, the pedal device 41 includes a cover member 80, and the cover member 80 is fixed to the lower surface 2b of the vehicle body 2 to cover the lower side of each support arm 47.

Specifically, the cover member 80 includes a bottom wall portion 81 disposed below each support arm 47, and a peripheral wall portion 82 provided so as to be substantially orthogonal to an edge portion of the bottom wall portion 81. The peripheral wall portion 82 extends upward toward the lower surface 2b of the vehicle body 2. In the lid member 80, the bottom wall portion 81 is formed in a size to cover the movable pedal 42 from below the support arms 47 when the movable pedal 42 is in the retracted position P1. The peripheral wall portion 82 is provided so as to extend on the vehicle front side, the vehicle width direction inner side, and the rear side, and to be substantially orthogonal to the edge portion of the bottom wall portion 81. Thus, the cover member 80 forms a storage space 83 that is open to the outside in the vehicle width direction below the lower surface 2b of the vehicle body 2.

Specifically, the cover member 80 is fastened to the lower surface 2b of the vehicle body 2 together with the support bracket 48 of each support arm 47. Further, the cover member 80 forms a housing space 83 between the lower surface 2b of the vehicle body 2 positioned above and the pedal portion 46 of the assist pedal 43. Thus, when the movable pedal 42 is at the retracted position P1, substantially the entire movable pedal 42 is stored in the storage space 83 together with the support arms 47.

When the movable pedal 42 is at the retracted position P1, the opening 83x of the storage space 83 facing the outside in the vehicle width direction is shielded by the exterior member 84 (see fig. 6) provided at the lower end of the slide door 4. Thus, the pedal device 41 is configured to prevent foreign matter from entering the housing space 83 through the opening portion on the vehicle width direction outer side when the vehicle 1 travels.

(holding mechanism of movable pedal)

Next, a holding mechanism of the movable pedal 42 will be described.

As shown in fig. 14 to 16, the pedal device 41 includes a holding mechanism 100, and the holding mechanism 100 can hold the movable pedal 42 at a retracted position P1 on the vehicle width direction inner side in a state where the guide roller unit 70 is detached from the guide rail 60 provided on the movable pedal 42, that is, in a state where the connection with the slide door 4 is released.

The holding mechanism 100 is provided to the cover member 80, and the cover member 80 forms the housing space 83 of the movable pedal 42 that has been moved to the retracted position P1. Specifically, the holding mechanism 100 is provided near the front end portion 80f of the cover member 80. The holding mechanism 100 includes an engaging member 111, and the engaging member 111 includes a lever member 110 that pivots about a support shaft 110x substantially perpendicular to the bottom wall portion 81 of the cover member 80. Then, in a state where the movable pedal 42 has moved to the retracted position P1, the engagement member 111 rotates about the support shaft 110x, and the engagement member 111 engages with the pedal-side engagement portion 120 provided in the movable pedal 42 and disengages from the pedal-side engagement portion 120. The engaging member 111 is movable between an unlock position X0 where it does not interfere with the movable pedal 42 that moves in the vehicle width direction, and a lock position X1 where the movable pedal 42 is held at the retracted position P1.

Specifically, the engaging member 111 includes a lever main body 131 extending in the vehicle width direction, and an engaging protrusion 132 protruding from a distal end portion 131a of the lever main body 131. A support shaft 110x is provided at a base end 131b of the lever main body 131. The engaging projection 132 extends in the circumferential direction of the support shaft 110 x. Specifically, the holding mechanism 100 includes a support shaft 110x of an engaging member 111 in the vicinity of the peripheral wall portion 82 located on the vehicle width direction inner side in the housing space 83 of the movable pedal 42 formed in the cover member 80. The engagement projection 132 projects toward the vehicle rear side (right side in the drawings) from a distal end portion 131a of the lever main body 131 extending toward the vehicle width direction outer side (lower side in the drawings).

As shown in fig. 17 and 18, an engagement recess 135 that opens toward the vehicle front side is provided at the front end portion 42f of the movable pedal 42. The engagement recess 135 is the pedal-side engagement portion 120. Then, the engagement member 111 moved to the lock position X1 is engaged with the movable pedal 42.

That is, in fig. 15 and 16, the engaging member 111 is moved from the unlock position X0 to the lock position X1 by rotating counterclockwise about the support shaft 110X. The engaging member 111 is moved from the lock position X1 to the unlock position X0 by being rotated clockwise about the support shaft 110X.

As shown in fig. 15 to 18, in a state where the movable pedal 42 has been moved to the retracted position P1, the engagement member 111 is rotated about the support shaft 110x, whereby the engagement projection 132 projecting from the distal end portion 131a of the lever main body 131 is inserted into and removed from the engagement recess 135 as the pedal-side engagement portion 120. Thus, the engaging member 111 can hold the movable pedal 42 at the retracted position P1 and can release the held state.

A chamfered portion 133 having a curved surface 133s is provided at the tip end of the engagement projection 132. Accordingly, in the holding mechanism 100, the engagement protrusion 132 can be smoothly inserted into and removed from the engagement recess 135 by the rotation of the engagement member 111.

As shown in fig. 19 and 20, the engaging member 111 is provided with an engaging claw 140 that protrudes from the base end 131b of the lever main body 131 in the radial direction of the support shaft 110 x. Specifically, the engaging pawl 140 has a triangular shape tapered toward the distal end side. The engagement claw 140 protrudes inward in the vehicle width direction. Further, a projection 141 projecting outward in the vehicle width direction is provided on the peripheral wall 82 of the cover member 80 facing the engagement claw 140. The protrusion 141 is provided at substantially the same position as the support shaft 110x of the engaging member 111 in the vehicle longitudinal direction. The engaging member 111 is held at the lock position X1 or the unlock position X0 by the engaging pawl 140 engaging with the protrusion 141.

That is, as shown in fig. 15 and 19, the projection 141 engages with the engagement pawl 140 of the engagement member 111 in a state where the engagement pawl 140 is positioned on the vehicle front side (left side in the drawings), and restricts rotation in the unlocking direction in which the engagement member 111 moves from the lock position X1 to the unlock position X0. Thus, the protrusion 141 serves as the position holding member 150 that holds the engaging member 111 at the lock position X1.

The protruding portion 141 includes a curved surface 142 with respect to the engaging surface 141s of the engaging pawl 140. The curved surface 142 is formed to have a substantially circular arc-shaped cross section bulging toward the support shaft 110x of the engaging member 111 located in the direction in which the protrusion 141 projects. The holding mechanism 100 can rotate the engaging member 111 in the unlocking direction based on the curved surface shape engaging force of the engaging surface 141s against the engaging force of the protrusion 141 and the engaging pawl 140. That is, the engagement claw 140 can be disengaged from the protrusion 141 so as to pass over the protrusion 141 by applying an operating force in the unlocking direction exceeding the engaging force with the protrusion 141 constituting the position holding member 150 to the engagement member 111. Accordingly, the engaging member 111 rotates clockwise in the drawings, and moves from the locked position X1 to the unlocked position X0.

As shown in fig. 16 and 20, the engagement claws 140 of the protrusions 141 engage with each other with the engagement claws 140 of the engagement members 111 positioned on the vehicle rear side (right side in the drawings), and rotation of the engagement members 111 in the locking direction in which the engagement members are moved from the unlock position X0 to the lock position X1 is restricted. Even in this case, an operation force in a locking direction exceeding the engaging force with the protrusion 141 of the position holding member 150 is applied to the engaging member 111, and the engaging pawl 140 can be disengaged from the protrusion 141 so that the engaging pawl 140 rides over the protrusion 141. As a result, the engaging member 111 rotates counterclockwise in the drawings, and moves from the unlock position X0 to the lock position X1.

As shown in fig. 17 and 18, a slip-preventing part 155 is provided at the tip of the lever main body 131. The nonslip portion 155 has a saw-toothed concave-convex shape 153. When the user performs the locking operation and the unlocking operation of the movable pedal 42 from the opening 83 of the housing space 83 facing outward in the vehicle width direction, the holding mechanism 100 can overcome the engaging force between the engaging member 111 and the position holding member 150, and can easily rotate the engaging member 111.

As shown in fig. 19 and 20, the engaging member 111 has a cross-sectional shape intersecting the longitudinal direction of the lever main body 131, and has an outer shape in the shape of a groove with a downward-facing cross-section. The holding mechanism 100 further includes a stopper 162 protruding from the lever support 160 provided in the cover member 80. The stopper 162 is disposed in an engaging recess 161 forming the cross-sectional shape of the engaging member 111. The stopper 162 engages with an inner wall surface of the engaging recess 161 provided in the engaging member 111, and limits the movement range of the engaging member 111 about the support shaft 100 x.

More specifically, as shown in fig. 21, when the movable pedal 42 moves from the outside to the inside in the vehicle width direction to the retracted position P1 in a state where the engaging member 111 has moved to the lock position X1, the engaging member 111 is pressed by the movable pedal 42 and moves from the lock position X1 to the unlock position X0.

That is, the engaging force of the position holding member 150 and the engaging member 111 is set to a value smaller than the driving force for moving the movable pedal 42 in conjunction with the opening and closing operation of the slide door 4. Thereby, the engaging member 111 is disengaged from the position retaining member 150 and is rotated in the unlocking direction by the pressing force of the movable pedal 42 moving to the retracted position P1.

Specifically, when the movable pedal 42 is pivoted to the retracted position P1, the movable pedal 42 moves from the outside toward the inside in the vehicle width direction while moving toward the vehicle front side in conjunction with the closing operation of the slide door 4. At this time, the tip end portion 132a of the engagement projection 132 is pressed by the movable pedal 42, and the engagement projection 132 that projects toward the vehicle rear side does not engage with the engagement recess 135 that constitutes the pedal-side engagement portion 120. Thus, the pressing force of the movable pedal 42 is efficiently converted into a force for rotating the engagement member 111 in the unlocking direction.

As shown in fig. 22, even when the movable pedal 42 moves outward in the vehicle width direction from the retracted position P1 in a state where the engaging member 111 is engaged with the movable pedal 42, the engaging member 111 rotates in the unlocking direction against the engaging force of the position holding member 150 in accordance with the driving force in conjunction with the opening operation of the slide door 4.

At this time, the movable pedal 42 moves outward in the vehicle width direction in a state where the inner wall surface 135s of the engagement recess 135 constituting the pedal-side engagement portion 120 presses the engagement protrusion 132 of the engagement member 111 inserted into the engagement recess 135. The engagement projection 132 is pulled out from the engagement recess 135 by an angle at which the engagement projection 132 is pressed by the inner wall surface 135s of the engagement recess 135. Thus, the force with which the movable pedal 42 moving outward in the vehicle width direction presses the engaging member 111 is converted into a force with which the engaging member 111 pivots about the support shaft 110X, and the engaging member 111 smoothly moves from the lock position X1 to the unlock position X0

Next, the operation of the present embodiment will be described.

In the holding mechanism 100, when the movable pedal 42 has moved inward from the vehicle width direction to the retracted position P1 while the engaging member 111 has moved to the lock position X1, the movable pedal 42 presses the engaging member 111 in the unlocking direction. In the engaged state of the engagement member 111 and the movable pedal 42, even when the movable pedal 42 moves outward in the vehicle width direction from the retracted position P1, the movable pedal 42 presses the engagement member 111 in the unlocking direction. Further, the movable pedal 42 moves from the lock position X1 to the unlock position X0, and smooth movement of the movable pedal 42 in conjunction with the opening and closing operation of the slide door 4 is ensured.

Next, the effects of the present embodiment will be described.

(1) The pedal device 41 includes a movable pedal 42, and the movable pedal 42 is supported below the door opening 3, is coupled to the slide door 4 via a guide roller unit 70 as a coupling member, and moves in the vehicle width direction in conjunction with the opening and closing operation of the slide door 4. The pedal device 41 includes an engaging member 111, and the engaging member 111 is engaged with the movable pedal 42 so as to be movable between a lock position X1 at which the movable pedal 42 is held at a retracted position P1 on the vehicle width direction inner side and an unlock position X0 at which the movable pedal 42 does not interfere with the movable pedal 42. Then, in a state where the engaging member 111 has moved to the lock position X1 and the movable pedal 42 has moved to the retracted position P1, the engaging member 111 is pressed by the movable pedal 42 and moved from the lock position X1 to the unlock position X0.

According to the above configuration, even when the engaging member 111 is moved to the lock position X1 by an erroneous operation or the like, for example, the engaging member 111 is formed so as not to interfere with the movement of the movable pedal 42 in conjunction with the closing operation of the slide door 4. This can form the holding mechanism 100 that can ensure smooth operation of the movable pedal 42.

(2) The engaging member 111 includes a lever member 110 that rotates about a fulcrum 110 x. Further, the engaging member 111 includes: a lever body 131 having a fulcrum 110 x; and an engagement projection 132 projecting from the lever main body 131 so as to extend in the rotational direction around the support shaft 110 x. When the movable pedal 42 is in the state of having been moved to the retracted position P1, the engagement member 111 rotates about the support shaft 110x, whereby the engagement projection 132 engages with the pedal-side engagement portion 120 provided on the movable pedal 42 and disengages from the pedal-side engagement portion 120. When the movable pedal 42 has moved to the retracted position P1 while the engagement member 111 has moved to the latched position X1, the distal end portion 132a of the engagement projection 132 is pressed by the movable pedal 42, and the pedal-side engagement portion 120 does not engage with the engagement projection 132.

According to the above configuration, the movable pedal 42 that moves inward in the vehicle width direction in conjunction with the closing operation of the slide door 4 can efficiently convert the force pressing the engaging member 111 into the force rotating the engaging member 111 about the support shaft 110 x. This allows the engaging member 111 to smoothly move from the locked position X1 to the unlocked position X0.

(3) The pedal device 41 includes a position holding member 150, and the position holding member 150 engages with the engaging member 111 to hold the engaging member 111 at the lock position X1. The engaging member 111 is configured to: when the movable pedal 42 moves from the retracted position P1 to the vehicle width direction outer side with the engaging member 111 engaged with the movable pedal 42, the engaging member 111 is disengaged from the position holding member 150 against the engaging force with the position holding member 150, and can move from the lock position X1 to the unlock position X0.

According to the above configuration, even when the movable pedal 42 moves in conjunction with the opening operation of the slide door 4 in a state where the engagement member 111 is engaged with the movable pedal 42 due to, for example, an erroneous operation, the engagement member 111 can be formed so as not to interfere with the movement of the movable pedal 42. This can form the holding mechanism 100 that can ensure smooth operation of the movable pedal 42.

(4) The engaging member 111 has an engaging claw 140 projecting in the radial direction of the support shaft 110 x. The engaging member 111 is provided on the bottom wall portion 81 of the cover member 80 that covers the lower side of the movable pedal 42 that has moved to the retracted position P1. The peripheral wall 82 of the cover member 80 is provided with a protrusion 141 protruding toward the support shaft 110x of the engaging member 111. The protrusion 141 engages with the engagement pawl 140, and serves as a position holding member 150 that restricts the movement of the engagement member 111 from the lock position X1 to the unlock position X0, that is, the rotation in the unlock direction. That is, the position retaining member 150 is a protrusion 141 provided to the cover member 80.

With the above configuration, the engaging member 111 can be stably disposed in the vicinity of the movable pedal 42 that has moved to the retracted position P1 with a simple configuration. Further, according to the above configuration, the position holding member 150 can be stably formed with a simple configuration. Further, the engaging claw 140 is provided on the engaging member 111, so that the engaging member 111 can be rotated about the support shaft 110x, and the position holding member 150 can be smoothly and stably engaged with and disengaged from the engaging member 111.

(5) The protrusion 141 as the position holding member 150 is engaged with the protrusion 141 from the locking direction opposite to the unlocking direction by the engaging pawl 140, and has a function of holding the engaging member 111 at the unlocking position X0 while restricting the rotation in the locking direction. Thus, with a simple configuration, the engaging member 111 that has moved from the locked position X1 to the unlocked position X0 can be held at the unlocked position X0.

(6) An engaging surface 141s of the protrusion 141 constituting the position holding member 150 with respect to the engaging pawl 140 includes a curved surface 142 having a substantially circular arc-shaped cross section bulging toward the support shaft 110x of the engaging member 111. This enables the engaging member 111 to be more smoothly and stably engaged with and disengaged from the position holding member 150.

(7) The pedal-side engaging portion 120 includes an engaging recess 135, and the engaging protrusion 132 is inserted into and removed from the engaging recess 135 by the engaging member 111 rotating about the support shaft 110 x. Then, in a state where the engagement projection 132 is inserted into the engagement recess 135, the movable pedal 42 moves outward in the vehicle width direction, and the engagement projection 132 is pulled out from the engagement recess 135 by the pressing force of the movable pedal 42.

According to the above configuration, the force with which the movable pedal 42 moving outward in the vehicle width direction in conjunction with the opening operation of the slide door 4 presses the engaging member 111 can be efficiently converted into the force with which the engaging member 111 pivots about the support shaft 110 x. This allows the engagement member 111 to smoothly move from the lock position X1 to the unlock position X0.

(8) A chamfered portion 133 having a curved surface 133s is provided at the tip end portion 132a of the engagement projection 132. Thus, the engagement protrusion 132 of the engagement member 111 can be smoothly inserted into and removed from the engagement recess 135 by the rotation around the support shaft 110 x.

(9) The pedal device 41 includes a stopper 162 that limits the range of movement of the engaging member 111. This can suppress the engagement member 111 held at the lock position X1 or the unlock position X0 from rattling.

(10) A nonslip portion 155 having a serrated concave-convex shape 153 is provided at the tip end of the lever main body 131.

According to the above configuration, when the user performs the locking operation and the unlocking operation of the movable pedal 42, the engaging member 111 can be easily rotated against the engaging force between the engaging member 111 and the position holding member 150.

The above embodiment can be modified and implemented as follows. The above-described embodiment and the following modifications are implemented in combination with each other within a range not technically contradictory.

In the above embodiment, the pedal device 41 is embodied so as to be interlocked with the rear-opening type slide door 4 that is opened toward the vehicle rear side, but the present invention can also be applied to the front-opening type slide door 4 that is opened toward the vehicle front side.

In the above embodiment, the sliding door 4 is driven by the electric sliding door device 31 to perform the opening and closing operation, but the present invention can also be applied to a sliding door 4 not having such an electric sliding door device 31.

The support structure of the movable pedal 42 may be changed as desired, for example, a rail or a slide type, as long as it is a structure that moves in the vehicle width direction in conjunction with the opening and closing operation of the slide door 4.

In the above embodiment, the engaging member 111 and the position retaining member 150 constituting the retaining mechanism 100 are provided in the cover member 80 covering the lower side of the movable pedal 42 moved to the retracted position P1, but the positions of the engaging member 111 and the position retaining member 150 may be changed as desired.

In the above embodiment, the engaging member 111 is formed to include the lever member 110 that rotates about the support shaft 110x, having the lever main body 131, the engaging protrusion 132, and the engaging claw 140, but this configuration may be modified as desired. For example, the engaging portion with respect to the pedal-side engaging portion 120 may have a shape different from the engaging projection 132, and the engaging portion with respect to the position retaining member 150 may have a shape different from the engaging claw 140. The present invention is not limited to the rotating lever, and may be a slide lever.

Further, the shape of the pedal-side engagement portion 120 and the formation position thereof may be arbitrarily changed. The shape and arrangement of the position holding member 150 are not limited to the projection 141 of the above embodiment, and may be arbitrarily changed.

In the above embodiment, the position holding member 150 has the function of holding the engaging member 111 at the lock position X1 and the function of holding the engaging member 111 at the unlock position X0, but another member may be used to hold the engaging member 111 at the unlock position X0.

Further, the structure of the stopper 162 may be arbitrarily changed.

For example, as shown in fig. 23, two protrusions 164, 165 are provided at two positions sandwiching the protrusion 141 constituting the position retaining member 150 in the vehicle front-rear direction. The projection 164 is disposed at a position that abuts against the engagement pawl 140 and restricts the range of rotation of the engagement member 111 when the engagement pawl 140 of the engagement member 111 that rotates about the support shaft 110X rotates in the locking direction beyond the lock position X1. The projection 165 is disposed at a position that abuts against the engagement pawl 140 and restricts the range of rotation of the engagement member 111 when the engagement pawl 140 of the engagement member 111 that rotates about the support shaft 110X rotates in the unlocking direction beyond the unlocking position X0. Thus, the respective projections 164, 165 can be used as the stopper 162B of the engaging pawl 140.
