PROBLEM TO BE SOLVED: To reduce noise by suppressing vibration transmitted to the side of a first unit attached to an upper face opening of a fuel tank from the side of a second unit arranged in the fuel tank.SOLUTION: A fuel supply device 10 comprises: a first unit 12 attached to an attachment hole of a fuel tank; a second unit 14 arranged in the fuel tank; and a connection mechanism 16 for movably connecting the second unit 14 to the first unit 12 in the vertical direction. The connecting mechanism 16 is constituted of a connecting shaft 38 arranged at the side of the first unit 12 and an elastic support member 40 arranged at the side of the second unit 14. The connecting shaft 38 is supported by a shaft attachment part 42 at the side of the first unit 12 in a state that its tip is directed toward the side of the second unit 14. The elastic support member 40 comprises: a base part 46 arranged at the side of the second unit 14; a shaft insertion part 50 allowing the insertion of the connecting shaft 38 so as be movable in the axial direction; and an elastic deformation part 48 for elastically supporting the shaft insertion part 50 to the base part 46. |
