Abstract: PROBLEM TO BE SOLVED: To provide a fuel supply system settable in fuel tanks having various depths.
SOLUTION: One end of a metal pipe 18 is pressed into the press-in part 16 of a mounting member 11, and engagingly locked by the mounting member 11. An E-ring 19 is attached to the other end of the metal pipe 18. When the mounting member 11 is separated from a filter case 32, the E-ring 19 is engagingly locked by the locking part 43 of an insertion part 33. Since a coil spring 20 energizes the mounting member 11 and the filter case 32 in the mutually separating directions along the axial direction of the metal pipe 18, the bottom of a sub-tank 22 is regularly pressed onto the inside bottom surface of a fuel tank 1. A projection part 24 protruded from the inside bottom surface is formed on the bottom inside of the sub-tank 22. When the mounting member 11 gets close to the filter case 32, the other end of the metal pipe 18 is engagingly locked by the projection part 34 of the sub-tank 22.

Abstract: PROBLEM TO BE SOLVED: To make a fuel supply device composed of a cover member and a pump module small and flat. SOLUTION: In the fuel supply device, a bellows pipe 50 is connected to a pipe connection part 15 or a pipe connection part 29 arranged roughly perpendicular to a center axis of the cover member 11 at both end parts thereof. Consequently, interference of the pipe connection part 15 with the pipe connection part 29, and interference of a pipe member 15 and a pipe member 29 with other member is reduced even if the fuel supply device 10 is a style supporting a pump module 20 on the cover member 11. Also, interference of the bellows pipe 50 and other member can be reduced. Consequently, the pipe connection part 12, the pipe connection part 29 and the bellows pipe 50 can be stored in a little space formed between the cover member 11 and the pump module 20 without causing interference between members. Consequently, total length in an up-and-down direction, namely in a depth direction of a fuel tank 1 can be reduced and the fuel supply device 10 can be installed in a flat fuel tank 1.

解决方案：在燃料供给装置中，波纹管50连接到管连接部15或者在其两端部大致垂直于盖构件11的中心轴布置的管连接部29。 因此，即使燃料供给装置10是支撑泵模块20的状态，也能够减少管连接部15与管连接部29的干涉，以及管构件15和管构件29与其他构件的干涉 也可以减小波纹管50与其他部件的干涉。 因此，管连接部12，管连接部29和波纹管50能够容纳在盖部件11和泵模块20之间形成的一小部分空间中，而不会造成部件间的干扰。 因此，可以减少上下方向的总长度，即在燃料箱1的深度方向上，并且能够将燃料供给装置10安装在平坦的燃料箱1中。（C） 2006年，JPO＆NCIPI

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.
