摘要： PROBLEM TO BE SOLVED: To provide a fuel supply device in which the harness of electric devices disposed in a fuel tank is hard to be damaged.
SOLUTION: A support member 90 is fitted to the projecting part 87 of a flange 22 closing the open part of the fuel tank. The harness 83, 84 is supported by the support member 90. The projecting part 87 of the flange 22 is formed in a cylindrical shape that can contain a cutoff valve for opening and closing the fuel vapor inlet of a canister. The support member 90 is snap-fit engaged with the projecting part 87 by utilizing the structure of snap fit engagement of the cutoff valve with the projecting part 87. Therefore, the portions of the harness 83, 84 supported by the support member 90 are restricted to move freely. Since the holding of the harness 83, 84 by a coiled spring in the fuel tank is suppressed, the possibility of damage to the harness 83, 84 can be reduced.

摘要： 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.

摘要翻译：要解决的问题：使由盖构件和泵模块构成的燃料供给装置小而平坦。
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

摘要： PROBLEM TO BE SOLVED: To provide a fuel feeder of less noise for easily connecting a pressure regulator to a jet pump.
SOLUTION: The fuel feeder 10 is accommodated in a fuel tank. Two projection parts having a claw 47 on a fuel discharge side 42 of a fuel pump 40 are formed at positions separate from each other in the circumferential direction. The claws 47 are fitted to and engaged with opening parts 38 formed in a filter case 32 to prevent the fuel pump 40 from being fallen from the filter case 32. The whole periphery on the fuel discharge side 42 of the fuel pump 40 is press-fitted to a cylindrical press-fitting part 37 of the filter case 32. A fuel suction side 48 of the fuel pump 40 is not supported by other components, but in a free state. A fuel inlet of a pressure regulator 60 is directly coupled with the fuel outlet of the filter case 32. A fuel outlet 62 of the pressure regulator 60 is directly coupled with a fuel inlet 72 of a jet pump 70 formed on the inner side of a bottom part of a sub tank 20.

摘要： PROBLEM TO BE SOLVED: To provide a miniaturizable fuel supply device for easily installing a fuel filter in a fuel tank.
SOLUTION: The fuel filter 20, a fuel pump 10 and a pressure regulator 40 are detachably installed. A filter case 21 of the fuel filter 20 is composed of an upper case 22 and a lower case 31. The upper case 22 and the lower case 31 are welded by a boundary part 29. The boundary part 29 is positioned in the fuel tank 1. The upper case 22 and the lower case 31 are respectively integrally molded except for a connecting pipe 37, and a cover part 25 is fitted to the fuel tank. Thus, since the number of part items is reduced by dispensing with the other member for installing the fuel filter 20 in the fuel tank 1, installation and removal man-hours are reduced, and manufacturing cost can also be reduced.

摘要： PROBLEM TO BE SOLVED: To provide a fuel filter combining the assurance of filtering performance and the extension of a service life with simple adjustment.
SOLUTION: Fuel passing through the fuel filter 30 flows from the outside to the inside of a filter body 31. The filter body 31 has an outer peripheral layer part formed of nonwoven fabric, and an inner peripheral layer part formed of filter paper. Comparatively large ones out of foreign matters included in the fuel are thereby captured in the outer peripheral layer part, and comparatively small ones are captured in the inner peripheral layer part. Consequently, clogging of the filter paper in the inner peripheral layer part is reduced. The desired filtering performance can easily be set by selecting the nonwoven fabric and filter paper. The assurance of filtering performance and the extension of the service life with simple adjustment can be combined. The outer edge of the filter body 31 is sealed with a molding part 32. A mounting part 50 for mounting a sub-tank 11 is installed at the molding part 32. Since the mounting part 50 is formed integrally with the molding part 32 at the same time, the number of parts is reduced.

摘要： PROBLEM TO BE SOLVED: To provide a fuel tank module suppressing damage of a bellows tube and generation of abnormal noise.
SOLUTION: In the fuel tank module disposed in a fuel tank, the bellows tube for supply flowing fuel in a sub tank to a common rail, and a bellows tube 40 for return flowing return fuel from the common rail into the sub tank. By inserting a protective tube 50 into the bellows tube 40 for return, an uneven part 42 for return of the bellows tube 40 for return is covered with the reticular protective tube 50. The uneven part 52 of fiber 51 of the protective tube 50 are lower than the uneven height of the uneven part 42 for return. Therefore, an uneven part for supply does not get hung up with the uneven part 42 for return, and problems of the wear of bellows tubes and generation of abnormal noise can be suppressed.
