おくことができて、組付け作業が容易になる。The evaporated gas from the separator of the fuel tank and the air vent of the fuel cock flows into the canister case via a breather valve with a hose, and is adsorbed on the canister. Thus, it is possible to prevent the evaporative gas of the fuel from leaking to the outside. The evaporative gas adsorbed in the canister case is connected to the canister case and the intake pipe of the engine via a hose, and is sucked and purged at a negative intake pressure during operation of the engine. The canister case and fuel cock are mounted on the shelves for mudguards, so the piping near the fuel tank can be shortened. Also, before attaching the mudguard to the car body,
Since the canister case and the fuel cock can be assembled to the mudguard, the assembling work becomes easy.

The fuel tank 1 is attached to a rear part of the vehicle body 2. Mudguards 4 covering the upper side of the rear wheel 3 are provided with shelves 5 on both left and right sides.
Are formed integrally so as to also serve as an undercover. The fuel tank 1 has a drain hose 6 attached to one side of a fuel filler port, and a separator 7 provided at an inner upper end so that evaporative gas is collected on the separator 7. The separator 7 extends to the front side of the fuel tank 1 with a pipe 8. An outlet 9 at a lower portion of the fuel tank 1 is connected to a float chamber of a carburetor 11 by a hose 10, and a fuel cock 12 is connected in the middle of the hose 10. The fuel cock 12 is a negative pressure cock that connects a negative pressure chamber to the carburetor 11 with a hose 13 and opens by suction negative pressure. The fuel cock 12 is attached to the left shelf 5.
