Zusammenfassung:	PURPOSE:To aim at an increase of strength in a joining part between a body and a rotary tank, by forming an embossing part in a position corresponding to a spot welding hole, and joining a tank body bottom surface part to an inner tank bottom surface part together by means of spot welding via this embossing part. CONSTITUTION:An embossing part 31f being projected to the side of a fuel tank body bottom surface part 21a is formed in an inner tank bottom surface part 31b at a position corresponding to a spot welding hole 30d of an outer tank bottom surface part 30c. A contact surface part 31g of the embossing part 31f is so designed as to come into contact with the fuel tank body bottom surface part 21a via the spot welding hole 30d of the outer tank bottom surface part 30c. An inner tank bottom surface part 31b is joined to the outer tank bottom surface part 30c as plural positions A is spot-welded whereby a rotary tank 22 is assembled. With this constitution, a joining part between the fuel tank body and the rotary tank 22 can be strengthened.
