ツトパイプ構造。 An automobile fuel comprising an inlet pipe body for injecting fuel into the fuel tank, and a breather pipe built into the inlet pipe body and discharging air from the fuel tank when fuel is injected. In the tank inlet pipe structure, the breather pipe is divided into an inlet pipe side breather pipe arranged on the inlet pipe main body side and a tank side breather pipe arranged on the fuel tank side. The structure is such that a breather pipe is connected, and one end of the tank side breather pipe is inserted from the lower end opening of the inlet pipe side breather pipe with a radial gap provided between the inner wall of the inlet pipe side breather pipe. The tank-side breather pipe is arranged such that the other end of the breather pipe located inside the tank is curved upward into the tank to form a curved part, and the other end opening is located at an upper part inside the tank. A small hole is formed at the lowermost part of the curved part, and a flexible tube that bends and becomes closed due to buoyancy due to rising fuel level is suspended from the small hole. Yuel tank inlet pipe structure.
