Fueling device

摘要

A fueling device comprises a resin passage-forming member configured to form a fuel path, a fuel path end member and a covering member. A resin sealing member constituting the fuel path end member is located on a filler port side of the fuel path and is welded to the passage-forming member about an axis of the fuel path to provide a seal against the passage-forming member by welding about the axis. The covering member is arranged to cover a welded part about the axis at which the sealing member is welded to the passage-forming member from outside of the fuel path with leaving a gap about the axis, which is formed between the welded part and the covering member and is divided into a plurality of sections. The covering member is protruded from an outer peripheral wall of the passage-forming member and is supported by the outer peripheral wall such as to form the gap. The covering member is linked with the outer peripheral wall of the passage-forming member by linkage sections formed between adjacent sections of the gap divided into the plurality of sections. This configuration suppresses deformation of a welded part between a pipe main body and an inner member by an external force.

主权项

1. A fueling device that supplies a fuel to a fuel tank, comprising:
a passage-forming member made of a weldable resin and configured to form a fuel path connecting to the fuel tank on a filler port side; a fuel path end member made of a resin, located on the filler port side of the fuel path, and attached to the passage-forming member about an axis of the fuel path to provide a seal against the passage-forming member by welding about the axis; and a covering member supported outside of an outer peripheral wall of the passage-forming member to cover a welded part and from outside of the fuel path leaving a gap about the axis, which is formed between the welded part and the covering member and is divided into a plurality of sections, wherein the covering member is arranged to cover the welded part continuously about the axis from outside of the fuel path even at positions between adjacent sections of the gap divided into the plurality of sections, such that sections of the covering member arranged to cover the welded part from outside of the fuel path at the positions between the adjacent sections of the gap are linked with the outer peripheral wall of the passage-forming member or such that the sections of the covering member arranged to cover the welded part from outside of the fuel path at the positions between the adjacent sections of the gap are arranged to cover the welded part with leaving a smaller gap than the gap.
