置。 In a vehicle equipped with a gasoline fuel tank, there is an on-off valve that is installed in the filler pipe and opens when a fuel injection gun is inserted into the filler pipe or the pressure inside the fuel tank exceeds a predetermined pressure; The filler pipe is provided with a sealing member that tightly contacts the outer peripheral surface of the fuel injection gun when inserted, and the opening/closing valve communicates with the canister to prevent evaporated fuel gas generated in the fuel tank during fuel injection and abnormalities. A device for preventing diffusion of evaporated fuel gas, characterized in that the evaporated fuel gas that is released when the pressure increases is guided to a canister to prevent the evaporated fuel gas from diffusing into the atmosphere.
