Abstract: A fuel tank has a superior outer appearance. A body and a bottom are aligned to each other in a vertical direction to form a sealed closed space for storing fuel between both members. The body is formed as a container having an opening in a downward direction. A connected end part is bent inward in a continuous manner from a lower end of its outer surface. The opening is covered from below with the bottom and its circumferential edge is overlapped on the connected end while its position is set and connected at its entire circumference by brazing.

Abstract: A fuel tank for a motorcycle includes a body panel, and a bottom plate. The bottom plate occludes an opening at a lower end of the panel and has an outer surface which is recessed inwards of the panel. A first junction flange portion which is integrally formed on a peripheral edge of the opening at the lower end of the body panel and a second junction flange portion which is integrally formed on an outer peripheral edge of the bottom plate, are superposed on each other and seam-welded to each other. The first and second junction flange portions are formed turned toward the center of the opening at the lower end of the body panel, so that they are not visible from the sides of the tank. Thus, the appearance of the fuel tank can be improved to enhance marketability, while enhancing the air-tightness of the tank and welding operability.
