This manufacturing method of a fuel tank is for manufacturing a metallic fuel tank having a concavo-convex portion in a course of seam welding using a seam welder, wherein the seam welding is performed using the seam welder provided with a non-interfering space where interference with the fuel tank is avoided, while changing the position of the fuel tank relative to the seam welder.

Manufacturing method of fuel tank, and fuel tank

A filler pipe for introducing a fuel from a fuel inlet to a fuel tank. Connected to the filler pipeis a bracket, which has a cross-section of a 'hat' shape and is constructed by bottom wall portions-located at its ends and is under a face to face contact with an outer surface of the filler pipeand an upper wall portion-located between the bottom wall portions-and spaced from the opposite outer surface of the filler pipe. The bottom wall portions-are welded to the opposed surface of the filler pipe. The brackethas a wing part-extending integrally from the upper wall part-and having a free end-' welded to the opposed surface of a breather pipe.
