A control valve controlling the opening operation of the valve port is arranged in the fuel inlet pipe. The control valve is normally closed. When a fuel pump nozzle is inserted into the fuel inlet, the control valve automatically opens, and the fuel vapor in the fuel tank is fed into the canister via the valve port.
