Abstract
A component attaching hole,is opened in the tank main body,constructed by laminating an inner shell,and an outer shell,via a fuel permeation preventing layer,, and the auxiliary component,is welded to the external surface of the tank main body,in such a manner as to cover the component attaching hole,. The component attaching hole is formed so as to be tapered in such a manner that the component attaching hole gets wider toward the external surface of the tank main body,, and a boss portion,is formed on the auxiliary component,which is tapered so as to fit in the component attaching hole,, whereby a fuel permeation preventing layer,laminated on the internal surface of the auxiliary component,is made to extend over the external surface of the boss portion,. When the tank main body,and the auxiliary component,are welded together, the fuel permeation preventing layer,on the external surface of the boss portion,is tightly joined to the fuel permeation preventing layer,exposed at the component attaching hole
