Abstract: A resin coupling connected to a resin fuel hose is provided. An O-ring is fitted in the inner cylindrical wall of the pipe inserting section of a coupling body. The electrical resistance of the coupling body meets 106 to 1010 &OHgr;·cm in volume resistivity, or 106 to 1010 &OHgr; in surface resistivity.

Abstract: An inlet filler pipe comprises a pipe main body having a fuel passage for fueling fuel through an inlet into a fuel tank, and a flange formed on the pipe main body, for attachment to an outer wheel housing. A reinforcing element comprising a plurality of first ribs and second ribs arranged so as to surround the pipe main body is formed on the flange. The portion along the outer periphery of the pipe main body between first ribs and second ribs serves as a fragile portion, ensuring breaks at a load over a predetermined level.

Abstract: Provided is a fuel cutoff valve that reduces the emission of fuel vapors from within fuel tanks. The fuel cutoff valve is mounted by partial insertion into a fixation hole provided in an upper tank wall of a fuel tank. The fuel cutoff valve comprises a cover, a casing, a float, and a spring. In the cover, a matrix of polyacetal having excellent resistance to fuel permeation reduces emission of fuel vapors into the atmosphere, while a dispersed phase of polyethylene in the matrix allows welding to fuel tank.

Abstract: An inlet filler pipe comprises a pipe main body 41 having a fuel passage 40b for fueling fuel through an inlet 40a into a fuel tank, and a flange 42 formed on the pipe main body 41, for attachment to an outer wheel housing 30. A reinforcing element 70 comprising a plurality of first ribs 72a and second ribs 74a arranged so as to surround the pipe main body 41 is formed on the flange 42. The portion along the outer periphery of the pipe main body 41 between first ribs 72a and second ribs 74a serves as a fragile portion 76, ensuring breaks at a load over a predetermined level.

Abstract: A fuel feeding mechanism of the present invention has an inlet filler pipe that runs from a filler opening formed in an outer side member of an automobile to a fuel tank. The inlet filler pipe has a flange. The inlet filler pipe is attached to an outer wheel house across a seal cup that is held between the flange of the inlet filler pipe and the outer wheel house. The inlet filler pipe is inserted from outside of the automobile through the filler opening toward the fuel tank and is attached to the outer wheel house. This arrangement enhances workability.

Abstract: A connector includes a body and a clip for fitting on the body. The body has a hose connecting portion and a pipe receiving portion. The pipe receiving portion is adapted to receive a pipe therein and includes a clip fitting part. The clip fitting part has an engaging hole for engagement with an engaging claw formed on the clip. The engaging claw moves from a protruded position for preventing removal of the pipe to a withdrawn position for permitting removal of the pipe from the pipe receiving portion as the operator forces the clip to be enlarged. An enlargement restraining device is provided that is operable to restrain the enlargement of the clip within a predetermined range, so that the clip can reliably resiliently return to the protruded position when the clip is released after the pipe has been removed from the pipe receiving portion.
