ABSTRACT:
A fuel tank of synthetic resin is provided with a holding plate of synthetic resin arranged within the tank, and an outside wall covering the holding plate and formed by blow molding. Parts such as a level gauge projecting from the outside wall and having a nipple portion are held to the holding plate. At the manufacturing state of the tank, parts are fixed to the holding plate, and in this state, a blow molding mold is set and the outside wall of the tank is formed by the blow molding. In this case, the outer periphery of the holding plate is fixed to the inner circumferential surface of the outside wall, and the inner circumferential surface of the outside wall is pressed to the outer circumferential surface of the nipple portion of the component part and the circumference of the nipple portion is sealed. And then the outside wall covering the top end surface of the nipple portion is cut thereby the tank is manufactured.
