[7. backseat pedal 136]

As shown in fig. 10 and 11, left and right pedal support portions 130 that support a rear seat pedal 136 are formed on the left and right fixing portions 50 formed on the seat frame 34. One pedal support portion 130 is disposed at each of the left and right positions of the rear suspension 104 in plan view. Further, a recess 132 is formed between the left and right fixing portions 50 below the plate-like guide portion 56 (fig. 7), and the recess 132 accommodates a rear seat pedal 136 (fig. 10) when not in use.

A set of rear seat pedals 136 is provided between the set of pedal support portions 130. The right rear seat step 136 is attached to the vehicle width direction inner side, i.e., the left side, of the right step support portion 130. The left rear seat step 136 is mounted on the vehicle width direction inner side, i.e., the right side, of the left step support portion 130.

The rear seat step 136 has a footrest 138 and an arm portion 140. The footrest section 138 is a member for the rider to place the feet. The arm portion 140 is interposed between the foot rest portion 138 and the pedal support portion 130 to connect the foot rest portion 138 and the pedal support portion 130. The arm 140 includes a base-end-side arm 142 and a tip-end-side arm 144.

The base end side arm portion 142 is rotatably supported by the pedal support portion 130. The connecting portion between the base end side arm portion 142 and the pedal support portion 130 is referred to as a first joint portion 146. In the first joint section 146, the base-end side arm section 142 rotates about the first rotation axis 148. The first rotating shaft 148 is substantially parallel to the vehicle width direction. Therefore, the rear seat pedal 136 rotates in the forward and backward direction about the first rotation shaft 148.

The distal-side arm portion 144 is rotatably supported by the proximal-side arm portion 142. The connecting portion between the distal-end side arm portion 144 and the proximal-end side arm portion 142 is referred to as a third joint portion 154. In the third joint portion 154, the distal end-side arm portion 144 rotates about the third rotation shaft 156. The third rotating shaft 156 is substantially perpendicular to the vehicle width direction. Therefore, the distal end side arm portion 144 is pivoted about the third pivot shaft 156 in the lateral direction, that is, in the direction from the inside toward the outside in the vehicle width direction and in the direction from the outside toward the inside in the vehicle width direction.

The footrest section 138 is rotatably supported by the tip-side arm section 144. The connection portion between the footrest section 138 and the distal arm section 144 is referred to as a second joint section 150. In the second joint unit 150, the footrest 138 rotates about the second rotation axis 152. In the state shown in fig. 10, that is, when the base-end side arm portion 142 is disposed on the rear side in the pivotal range and the tip-end side arm portion 144 is disposed on the outer side (right side) in the vehicle width direction in the pivotal range, the second pivot shaft 152 of the right rear seat step 136 extends from the left diagonally rear side to the right diagonally front side. Therefore, the foot rest 138 of the right foot pivots about the second pivot shaft 152 between the accommodated position on the vehicle width direction inner side and the deployed position on the vehicle width direction outer side (right side). The left rear seat step 136 is left-right opposite the right rear seat step 136.

With this configuration, the state of the rear step 136 changes between the accommodated state (fig. 11) accommodated in the recess 132 on the vehicle width direction inner side with respect to both ends on the vehicle width direction outer side of the seat frame 34 and the deployed state (fig. 10) deployed on the vehicle width direction outer side with respect to both ends on the vehicle width direction outer side of the seat frame 34. When the rider rides the vehicle, the rear seat step 136 is moved from the accommodated position to the deployed position.

As shown in fig. 3, in the deployed state of the rear seat step 136, the first joint section 146 and the first rotating shaft 148 (fig. 10) are arranged at positions forward of the pivot shaft 46. The second joint unit 150 is disposed at a position rearward of the pivot shaft 46.

The third joint portion 154 may not be provided in the arm portion 140. For example, the arm portion 140 may be rotatable about the first rotation shaft 148 in the front-rear direction, and the footrest portion 138 may be rotatable about the second rotation shaft 152 in the vehicle width direction inward and outward directions.

[8. Structure of the periphery of handlebar 94 ]

As shown in fig. 12, a handle 160, a brake lever 162, a knuckle guard (knuckle guard)164, a periphery display 166, and a camera 168 are provided at the right and left portions of the handlebar 94. The structure of the right part and the structure of the left part are bilaterally symmetrical. Hereinafter, the structure of the periphery of the right portion of the handle bar 94 will be described with reference to fig. 13 to 17 as appropriate, with fig. 12 as the center.

The handle 160 is provided at a position on the axis of the handlebar 94 and at an end portion of the handlebar 94 on the outer side in the vehicle width direction. A guard stay 172 is attached to an outer end portion of the handle 160 in the vehicle width direction. The protective stay 172 extends forward from the handle 160 and supports the knuckle guard 164. The knuckle guard 164 is disposed apart from the handle 160 at a position forward of the handle 160. For example, as shown in fig. 14 and 15, the knuckle guard 164 includes: a guard upper end 164a located at an upper end of the knuckle guard 164; a guard lower end portion 164b located at a lower end of the knuckle guard 164; and a convex portion 164c that protrudes further forward than the guard upper end portion 164a and the guard lower end portion 164b in a side view. The knuckle guard 164 and the guard stay 172 may be formed separately or integrally.

A camera 168 is attached to a portion of the handle 160 on the outer side in the vehicle width direction. The camera 168 is fitted into the shield stay 172 itself, or into the handle 160 or the handlebar 94 on the vehicle width direction inner side of the shield stay 172. That is, the camera 168 is disposed inward of the vehicle width direction outer end of the protective stay 172. According to this configuration, even if the camera 168 is laterally in contact with the handle bar 94, the end of the shielding stay 172 can protect the camera 168. The lens of the camera 168 is exposed to the outside with the optical axis directed to the rear right of the vehicle 10. The camera 168 captures the surroundings of the vehicle 10 on the rear side of the handlebar 94.
