The fuel tank is located lower than a seat surface of the seat. The canister adsorbs evaporation gas generated by evaporation of fuel inside the fuel tank. The breather pipe includes an inlet connected to the canister, and an outlet located at a higher position than the seat surface of the seat and open to the atmosphere. The drainpipe includes a drain hole located lower than the outlet, and branches from the breather pipe.

Vehicle

A vehicle includes a pair of front wheels, a frame portion, a drive source, a pair of suspension assemblies, a pair of drive shafts, a steering wheel, and a transfer mechanism which transfers movement of the steering wheel to the pair of front wheels. Each of the pair of suspension assemblies includes an upper arm supported pivotably by the frame portion, a lower arm supported pivotably by the frame portion below the upper arm, and a knuckle arm connecting the upper arm and the lower arm to each other. The transfer mechanism includes a steering shaft portion extending from the steering wheel and rotates with the steering wheel, a rack-and-pinion portion provided at a tip region of the steering shaft portion, and a pair of tie rods extending in a width direction of the vehicle and connecting the rack-and-pinion portion to the pair of knuckle arms. Each of the pair of drive shafts passes through between the upper arm and the lower arm, whereas each of the pair of tie rods passes above the upper arm.

A vehicle includes a pair of front wheels, a pair of rear wheels, a frame portion, a first seat portion, a second seat portion, a third seat portion, a steering wheel, and a grab bar. The first seat portion, the second seat portion and the third seat portion are supported by the frame portion and are disposed side by side in this order in a width direction of the vehicle. The steering wheel is in front of the first seat portion. The grab bar is on a side closer to the third seat portion in the width direction of the vehicle when viewed from the steering wheel. The grab bar includes a first grip portion in front of the second seat portion.

A vehicle includes a pair of front wheels, at least a pair of rear wheels, a frame portion supported by the pair of front wheels and the pair of rear wheels, a first seat portion and a second seat portion supported by the frame portion and arranged side by side in a width direction of the vehicle, a steering wheel in front of the first seat portion, and a roll-over protection cage supported by the frame portion and covering the first seat portion, the second seat portion and the steering wheel. The first seat portion includes a first seat back portion which has a first backrest surface. The second seat portion includes a second seat back portion which has a second backrest surface. The first seat portion and the second seat portion are adjacent to each other in a width direction of the vehicle. At a height of a lower end of the steering wheel, a center of the second backrest surface is at a more rearward position than a center of the first backrest surface.

A vehicle includes a pair of front wheels, a pair of rear wheels, a frame portion, a seat unit including a first seat portion and a second seat portion arranged side by side in a width direction of the vehicle and supported by the frame portion, a steering wheel in front of the first seat portion, a roll-over protection cage supported by the frame portion to cover an area above the seat unit and the steering wheel, and a shoulder bolster portion. The first seat portion includes a seat bottom portion that supports a human body from below, and a back support portion that supports the human body from behind. In the width direction of the vehicle, at least a portion of the shoulder bolster portion is on an outer side of the seat unit. In a side view, at least a portion of the shoulder bolster portion is at a more rearward position than a forward end of the seat bottom portion, at a more forward position than the back support portion, at a higher position than a center of the steering wheel in an up-down direction, and at a lower position than an upper end of the steering wheel. The shoulder bolster portion has its upper end at a higher position than a midway point between a center of an upper surface of the seat bottom portion and an upper end of the back support portion in an up-down direction.

A vehicle includes a pair of front wheels, at least a pair of rear wheels, a frame portion supported by the pair of front wheels and the pair of rear wheels, a roll-over protection cage supported by the frame portion, a cargo bed supported by the frame portion pivotably behind the roll-over protection cage, an engine supported by the frame portion below the cargo bed, an output adjuster disposed below the cargo bed to adjust an output of the engine, and a protective member disposed between the cargo bed and the output adjuster. The protective member overlaps at least a portion of the output adjuster but does not overlap at least a portion of the engine in a plan view.

A vehicle includes a pair of front wheels, a pair of rear wheels, a frame portion, a first seat portion, a second seat portion, a third seat portion, a roll-over protection cage, and a three-point type seat belt unit for the second seat portion. The first seat portion, the second seat portion and the third seat portion are supported by the frame portion and disposed side by side in this order in a width direction of the vehicle. The roll-over protection cage is supported by the frame portion to provide covering above the first seat portion, the second seat portion and the third seat portion.

A power steering device for a vehicle includes an input shaft () linked to a steering wheel, an output shaft () linked to a vehicle wheel, a torsion bar () that connects the input shaft () to the output shaft (), and a cylindrical member () supported by a housing () that is fastened to a vehicle body. The input shaft () includes a first input shaft () that is inserted into the cylindrical member (), supported rotatably by the cylindrical member (), and linked to the steering wheel, and a second input shaft () that connects the first input shaft () to the torsion bar (). A connection portion between the first input shaft () and the second input shaft () is constituted such that a rotation of the first input shaft () is transmitted to the second input shaft () and the first input shaft () is free to move in an axial direction relative to the second input shaft ().
