Abstract: An insert ring is mounted on a resin-made fuel tank body, the insert ring has seat surfaces for mounting a fuel pump thereon and boss holes formed in the seat surfaces. An insert molded body is formed by insert molding of the insert ring using a first resin material while leaving the boss holes and the seat surfaces exposed. The insert molded body is inserted into an outer surface of the fuel tank body by insert molding using a second resin material which forms the fuel tank body.

Abstract: A rubber composition containing 100 parts by weight a sulfur-vulcanizable rubber (A) and 0.1 to 30 parts by weight of a vulcanization agent of a cyclic polysulfide (B) having the formula (I): wherein R is a substituted or unsubstituted C2 to C20 alkylene group, substituted or unsubstituted C2 to C20 oxyalkylene group or alkylene group having an aromatic ring, n is an integer of 1 to 20, x is a number of 2 to 6 on average.

Abstract: To surely insert a fastening member into a fuel tank by sufficiently feeding a resin to every corner of the fastening member using a simple method. An insert ring is mounted on a resin-made fuel tank body, the insert ring has seat surfaces for mounting a fuel pump thereon and boss holes formed in the seat surfaces. An insert molded body is formed by performing insert molding of the insert ring using a first resin material in a state wherein the boss holes and the seat surfaces are exposed. The insert molded body is inserted into an outer surface of the fuel tank body by insert molding using a second resin material which forms the fuel tank body.
