Abstract
A fixation member configured to fix a filler pipe to the vehicle body includes a flexural deformation portion. In a non-surrounded state, this flexural deformation portion is not flexurally deformed but is located on the inner side of the outer circumference of a filler neck body. In a surrounded state, the flexural deformation portion is flexurally deformed to induce a pressing force and provides the pressing force to the filler pipe. This configuration suppresses rattling of the filler pipe over a long time period.
Claims3
A fuel supply apparatus, comprising:
- a resin filler pipe configured to form a fuel passage from a filler port to a fuel tank;
- and
- a metal fixation member configured to fix the filler pipe to a vehicle body, wherein
- the fixation member includes a surrounding portion configured to surround outside of at least part of the filler pipe, and a fixation portion configured to fix the surrounding portion to the vehicle body,
- at least part of the surrounding portion is formed as an elastically deformable flexural deformation portion,
- in a non-surrounded state the surrounding portion does not surround outside of at least part of the filler pipe, in a surrounded state the surrounding portion is arranged to surround outside of at least part of the filler pipe, in the non-surrounded state at least a part of the flexural deformation portion curves inward in a radial direction to a position where the outer circumference of the filler pipe is located in the surrounded state, and in the surrounded state the flexural deformation portion is located less inward in the radial direction than in the non-surrounded state, and
- the flexural deformation portion includes a flexural curved piece that is formed to be flexurally deformable by bending a partial region of the surrounding portion toward the filler pipe.
