PROBLEM TO BE SOLVED: To provide a tank cap for a fuel tank capable of reducing noise by effectively attenuating the transmitted vibration and properly maintaining mounting property to an oil feed port. SOLUTION: The tank cap for the fuel tank has a tank cap body 1; an engagement member 2 for engaging the tank cap body 1 with the oil feed port 6a by engaging with a part to be engaged of the oil feed port 6a; and a packing member 3 for sealing the oil feed port 6a by abutting on the approximately whole area of an edge 6b of the oil feed port with a predetermined pressure in the state where the engagement member 2 is engaged with the part to be engaged of the oil feed port 6a. A projection 3aa comprising an elastic member is formed on an upper part of the packing member 3 and the engagement member 2 is abutted on the tank cap body 1 in the state where the engagement member 2 is engaged with the part to be engaged of the oil feed port 6a. Thereby, it has a predetermined deflection amount. COPYRIGHT: (C)2005,JPO&NCIPI
