摘要： A movement permitting section is provided at a nozzle guide 22 at an interior of an inlet pipe 14. When a stopper 24 receives pushing force toward a fuel tank side from a refueling nozzle 18, the movement permitting section deforms so as to permit movement of the stopper 24 toward a radial direction outer side of the nozzle guide 22 or toward a fuel tank side.

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.

摘要： An object is to suppress excessive insertion of a fueling nozzle during fueling. A nozzle guide configured to form a nozzle guide path that guides a fueling nozzle is placed inside of a filler neck main body configured to include a fuel passage that introduces a fuel supplied from the fueling nozzle toward a fuel tank. This nozzle guide comprises a first projection for nozzle restriction provided on a nozzle guide end opening portion at an end of the nozzle guide path along a nozzle guide direction and protruded from an end opening circumferential wall of the nozzle guide end opening portion to narrow at least part of a diameter of the nozzle guide path; and a second projection for nozzle restriction provided on a downstream side of the first projection along the nozzle guide direction and protruded from the end opening circumferential wall to narrow at least part of the diameter of the nozzle guide path.

摘要： A fuel supply system includes a filler neck that is provided in a filler neck body formed in a tubular shape and has a pipe connection structure. A first member is formed separately from the filler neck. A second member is formed separately from the filler neck to be different from the first member. The first member and the second member are engaged with each other. At least one of the first member and the second member includes a protective portion that is configured to cover at least part of the pipe connection structure in a state that the first member and the second member are engaged with each other and positions of the first member and the second member are fixed relative to the filler neck. This configuration suppresses damage of the pipe connection structure that is connected with the filler neck in the fuel supply system.

摘要： 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.

摘要： A fuel supply apparatus comprises a filler neck body including a hollow fuel passage-forming structure configured to form a fuel passage and a fuel vapor port branched off from the fuel passage-forming structure; and a nozzle guide formed in a tubular shape to introduce a fueling nozzle. The nozzle guide includes a vapor flow path portion configured to introduce fuel vapor flowing into the fuel vapor port in a tank direction. The vapor flow path portion has a slow-down portion configured to slow down the fuel vapor introduced in the tank direction.

摘要： A fueling device comprises a filler neck that is configured to form a fuel flow path, a cover member, and a restraint portion. An engagement projection provided as an engagement portion of the cover member is engaged with an engaged recess provided as an engaged portion of the filler neck, so that the cover member is mounted to the filler neck on an opening side of the fuel flow path. The restraint portion is configured to restrain the cover member including an engagement extension portion downstream of the engagement projection in the fuel flow path to an outer circumferential wall of the filler neck. This configuration suppresses expansion and deformation of the cover member and avoids separation of the cover member from the filler neck, while maintaining the mounting property of the cover member.

摘要： A fueling device includes a fuel passage-forming member and a flap valve mechanism. The flap valve mechanism includes an opening-forming member attached to one end of the fuel passage-forming member and an opening-closing mechanism to open and close a filler inlet of the opening-forming member. The fuel passage-forming member includes a pipe body containing a resin inner layer in a pipe shape made of a first resin material and a resin outer made of a second resin material, and a welding end formed on an opening end of the pipe body. The opening-forming member includes a cover member that covers the opening end of the pipe body and a welded end formed on an opening end of the cover member and welded to the welding end. The cover member is made of a third resin material welded to either one of the first resin material and the second resin material.

摘要： A filler pipe is attached to a retainer that holds a fuel nozzle holder. The retainer includes: a first attaching portion attached to an inlet portion of the filler pipe; a holding portion having an engaging hole; and an opening positioned at a first end of the retainer, which is closer to a longitudinal center of the filler pipe than a second end is. The fuel nozzle holder includes: a second attaching portion and including an engaging piece that engages the engaging hole; and a main body extending from the second attaching portion toward the longitudinal center of the filler pipe. The engaging piece is surrounded at three sides by a groove having a U-shape. The engaging piece is connected to the second attaching portion on the main body-side. The holding portion extends toward the longitudinal center of the filler pipe to cover the groove.
