Abstract
A fuel tank comprises an upper-half tank body () and a lower-half tank body () which are made of bowl-shaped steel plates and which integrally include a flange () and a flange () in their peripheral edges, respectively, the flanges () being superposed on and liquid-tightly connected to each other. The flanges () are connected together by crimping into a roll shape to form an annular thick-walled connection (), and an annular reinforcing rib () leading to the connection () is formed at least in one of the upper-half and lower-half tank bodies (). Thus, it is possible to provide a fuel tank in which a sufficient strength can be imparted to portions around a flange connection, without particularly increasing the thickness of a steel plate.
