Abstract

The problem to be solved is to provide a fuel feeding device for vehicles that is stably secured to a vehicle body. In the fuel feeding device for vehicles having an inlet filler pipe 1 and a fixing member 4 , a flexible element 5 is provided that relatively presses the inlet filler pipe 1 toward the fixing member 4 . With the flexible element 5 causing the inlet filler pipe 1 and the fixing member 4 to make pressure contact with each other, there can hardly be any gap created between the inlet filler pipe 1 and the fixing member 4 irrespective of the difference in linear expansion coefficient between them.

First claim

What is claimed is:

1. A fuel feeding device for vehicles comprising:
an inlet filler pipe made of resin and having a fuel supply passage;
a fixing member that secures said inlet filler pipe to a vehicle body; and
a flexible element that relatively presses said inlet filler pipe toward said fixing member by undergoing elastic deformation to bring said inlet filler pipe into pressure contact with said fixing member, wherein
said flexible element presses one or both of said inlet filler pipe and said fixing member in a direction away from said flexible element,
said inlet filler pipe and said fixing member contact each other on a front side or a back side in a pressing direction of said flexible element,
said inlet filler pipe comprises a pipe body having said fuel supply passage, and a collar separate from said pipe body and attached to outside of said pipe body, and
said flexible element is integral with said collar and relatively presses said pipe body toward said fixing member.

2. A fuel feeding device for vehicles comprising:
an inlet filler pipe made of resin and having a fuel supply passage;
a fixing member that secures said inlet filler pipe to a vehicle body; and
a flexible element that relatively presses said inlet filler pipe toward said fixing member by undergoing elastic deformation to bring said inlet filler pipe into pressure contact with said fixing member, wherein
said flexible element forms part of one of said inlet filler pipe and said fixing member,
said flexible element itself makes pressure contact with the other one of said fixing member and said inlet filler pine,
said flexible element includes at least one protrusion that protrudes in a radial direction of said inlet filler pipe and elastically deforms circumferentially or axially, and
said inlet filler pipe and said fixing member include a recess for holding said flexible element in an elastically deformed state.

3. A fuel feeding device for vehicles comprising:
an inlet filler pipe made of resin and having a fuel supply passage;
a fixing member that secures said inlet filler pipe to a vehicle body; and
a flexible element that relatively presses said inlet filler pipe toward said fixing member by undergoing elastic deformation to bring said inlet filler pipe into pressure contact with said fixing member, wherein
said flexible element forms part of one of said inlet filler pipe and said fixing member,
said flexible element itself makes pressure contact with the other one of said fixing member and said inlet filler pipe, and
said flexible element is formed of part of said inlet filler pipe in the form of bellows.
