簡易な工程で実施出来る効果をもつ。(Operations and Effects of the Invention) The present invention is characterized in that a fuel tank with an integrally protruding fuel supply pipe is molded by blow molding using a thermoplastic synthetic resin as a material, and the tank is free from thermal deformation during molding or even for one moment after molding. Focusing on this, the tubes such as the preserver tube that are essential in the fuel tank are tightly surrounded and fixed using the above-mentioned thermal deformability, so that the surrounding and fixed part of the tube corrodes without force. There is no fear, and the effect is that permanent fixation can be carried out in an extremely simple process by attaching and fixing without causing material damage.
