Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a fuel tank cap which can reduce the possibility of fuel leakage further while allowing the outside air to come in and is immovable even in the case where a high-pressure car washing is made. SOLUTION: For the fuel tank cap 1 comprising a cap body 2 for covering and closing a fuel injection port of a fuel tank mounted on a car and a ring-like packing 3 provided at the cap body 2 and stuck to the periphery of the fuel injection port for sealing, an air induction passage 28 for inducting the outside air into the fuel tank is formed between the cap body 2 and the ring-like packing 3 and a lip closing valve 33 is provided, extending in a loop-like shape from the inner circumferential side of the ring-like packing and being pressed at its tip constantly against the inner wall 36 of the cap body 2, so as to induce the outside air by opening the air induction passage 28 when the pressure inside the fuel tank becomes negative.
