The armrest portion 201 can be easily attached to the front upper frame 182, the upper inclined frame 187, the front attachment bracket 191 and the rear attachment bracket 192.

  Therefore, the assembling property to the front upper frame 182, the upper inclined frame 187, the front mounting bracket 191 and the rear mounting bracket 192 can be improved as compared with the left and right integrated arm rest portion 201.

Furthermore, the present invention is characterized in that a rib 358 is provided on the inner surface of the armrest portion 201.
Thereby, the strength and rigidity of the armrest part 201 can be improved by the ribs 358.

Furthermore, the present invention is characterized in that the armrest portion 201 is made of resin.
Thereby, while being able to manufacture the armrest part 201 easily, the armrest part 201 can be made lightweight.

Furthermore, in the present invention, the side support members 85L and 85R are disposed on the rear seat 13, and stoppers 106 and 107 for restricting forward movement of the occupants 95 and 96 seated on the rear seat 13 are provided at the front portion of the armrest portion 201. It is installed.
Thereby, it is not necessary to provide a special frame for attaching the stopper, the number of parts can be reduced, and the cost can be reduced.

Next, the operation of the intake device 146 described above will be described.
9 (a) and 9 (b) are operation diagrams showing the operation of the intake device according to the present invention.
In (a), the power unit 18 is swingable via a bolt 139 to a bracket 132 attached to the vehicle body frame 11 (see FIG. 1) (actually, the bolt 139 and the inner peripheral side of the rubber bush 134 are integrated with each other). Accordingly, the rubber of the rubber bush 134 is twisted around the bolt 139 and the power unit 18 swings.) The bellows tube 156 provided in the intake device 146 includes an air cleaner 154 attached to the power unit 18 and the vehicle body. An intake box 157 attached to the frame 11 side is connected. The length of the bellows portion 165 of the bellows tube 156 before the power unit 18 swings is L1.

  (B) shows a state in which the power unit 18 swings in the direction of arrow A around the bolt 139. As the power unit 18 swings, a compressive force acts on the bellows tube 156, the bellows portion 165 contracts in the direction of arrow B, and the length thereof is L2 (L2 <L1).

In the above (a) and (b), the bellows tube 156 is disposed in the vicinity of the bolt 139 that is the swing center of the power unit 18 and above the bolt 139, so that almost no bending force acts on the bellows tube 156. Since the bellows portion 165 is expanded and contracted by applying a compressive force, the durability of the bellows tube 156 can be improved.
In addition, since the change in the cross-sectional area of the bellows part 165 due to the swing of the power unit 18 is small, the intake resistance does not change due to road surface unevenness.

  The side support structure of the seat of the present invention is suitable for a four-wheeled vehicle.
