Abstract

PURPOSE:To solve the necessity to separately prepare a sub-tank, simplify a structure, and reduce the cost by blow-molding a fuel reservoir side wall surrounding the intake section of a fuel pump and serving as the sub-tank integrally with a tank case. CONSTITUTION:A fuel tank is integrally provided with a side wall 3 surrounding the intake section 2a of a fuel pump 2 at the center section on the bottom face 1a of a tank case 1 to form a chamber 4 serving as a sub-tank in the side wall 3. Both end sections 3a and 3b of the side wall 3 are overlapped each other at the preset gap 11, the tip of one end section 3a is extended to the right side wall 3c, and the tip of the other end section 3b is extended to the position at the preset gap 12 from the left side wall 3d. The side wall 3 is blow-molded by a lower mold with protruded sections having the same shape. The fuel tank thus formed is installed on a vehicle body so that the overlapped section of both end sections 3a and 3b of the side wall 3 is faced to the front F or the rear R of a vehicle.
