Abstract: PROBLEM TO BE SOLVED: To provide a fuel supply system with reduced sliding resistance between a connection member and a supporting portion, performing smooth relative movement between a lid member and a pump unit.
SOLUTION: A flange 11 and a sub tank 20 having a fuel pump 40 are connected to each other via a metal pipe 16 in a relatively movable manner in the axial direction of the metal pipe 16. The metal pipe 16 is inserted in a hole portion 35 formed in a case cover 34 of a pump unit. The metal pipe 16 is guided to be moved in the axial direction by the slide of the metal pipe with an inner circumferential surface 51 of a supporting portion 50 formed on the outer circumferential side of the hole portion 35. A notched portion 52 to divide the inner circumferential surface 51 in the circumferential direction is formed on the inner circumferential side of the supporting portion 50. Therefore, even when the metal pipe 16 is inclined in the hole portion 35, the metal pipe 16 is not touched with the inner circumferential surface 51 in a portion corresponding to the notched portion 52, and the sliding resistance is reduced thereby. The relative movement between the flange 11 and the pump unit becomes smooth.

Abstract: PROBLEM TO BE SOLVED: To attach a liquid-level detector to a fuel tank as a unitary body with a fuel supply pump without attaching work such as screw tightening. SOLUTION: In this attaching structure, a protruding member 4, a holding piece 8 for holding an attaching surface 3a and a plurality of pawls 10a are provided as the first engaging means at a body 5 of a liquid-level detector, and a groove 6 and receiving parts 10b are provided as the second engaging means at the attaching surface 3a of an attaching member 3. Furthermore, the thickness of the protruding member 4 in the direction of the groove 6 is set so that the width is equal to or slightly larger than the width of the groove 6. The interval between the holding piece 8 and the contact surface is set so that the interval is equal to or slightly smaller than the plate width of the attaching surface 3a. Thereafter, when the protruding member 4 is inserted into the groove 6, the body 5 and the attaching member 3 are elastically coupled and engaged. Thus, the secure attachment is obtained so that looseness, deviation and disengagement can be prevented when large vibration occurs.
