Abstract
A fuel tank capable of strongly fusion-bonding a built-in part to an inner surface of an outer wall thereof while protecting the outer wall even when an impact, etc. are applied thereto. In the fuel tank for a motor vehicle, which is formed by blow molding, in which the built-in part is mounted, and which has the outer wall composed of a synthetic resin, a plurality of mounting members adapted to mount the built-in part to the fuel tank are provided on the built-in part so as to be fusion-bonded to the inner surface of the outer wall of the fuel tank. An abutment portion is formed on each of the mounting members for contacting the inner surface of the outer wall of the fuel tank, and an abutment surface and a plurality of abutment pins, each projecting from the abutment surface, are formed in the abutment portion. The abutment pin is formed into a columnar or frustum-shaped configuration, each having a circular or elliptical cross-section, and a diameter or a main axis of a projecting end of the abutment pin along with the height of the abutment pin from the abutment surface are formed less than the thickness of the outer wall of the fuel tank.
