る蒸発燃料ガス拡散防止装置。 In a vehicle equipped with a gasoline fuel tank, a seal member is provided in the filler pipe to prevent the diffusion of evaporated fuel gas to the atmosphere when the fuel injection gun is inserted, and the fuel injection gas is inserted or the internal pressure of the fuel tank is higher than a predetermined pressure. It is equipped with an on-off valve that opens when the valve is injected, and a negative pressure valve that is placed inside the case of the on-off valve and opens when the pressure inside the fuel tank exceeds a predetermined negative pressure. The evaporated fuel gas that escapes when the pressure rises is guided to the canister and adsorbed, thereby preventing the evaporated fuel gas from dispersing into the atmosphere and protecting the fuel tank from damage due to abnormal pressure rise or abnormal negative pressure. Characteristic evaporative fuel gas diffusion prevention device.
