An automotive member or a feed oil pipe includes: a member made of a ferritic stainless steel containing predetermined components containing 10.5% to 18.0% of Cr in mass %; a metal fitting made of an aluminized stainless steel sheet, the metal fitting being attached to the member; and a gap structure defined between the member and the metal fitting, the gap structure being exposed to a chloride environment, where the metal fitting has an Al-plating weight per unit area of 20 g/m.sup.2 or more and 150 g/m.sup.2 or less on a surface corresponding to a gap of the gap structure, and surfaces of the metal fitting and the non-aluminized member other than the gap are coated with a cation electrodeposition coating film having a thickness of 5 m to 35 m.

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.

An oil filler port of the capless oil feeder includes: an oil filler port main body made of a resin, a breather tube portion made of the resin, and a flap valve. The oil filler port main body has a tubular shape and includes a nozzle insertion port for inserting an oil filler nozzle at one end and a fuel feed port for supplying fuel to a filler tube at the other end. The breather tube portion is formed integrally on an outer side of a peripheral surface of the oil filler port main body and connected to a breather tube. The flap valve is foamed to be insertable from the fuel feed port, and is disposed inside the oil filler port main body to close the nozzle insertion port and is opened by insertion of the oil filler nozzle.

A fuel tank includes an outer component including an outer panel forming a tank outer shell and an inlet plate formed separately from the outer panel, an inner component including an inner panel forming a tank inner shell and an inner connection plate formed separately from the inner panel, and a pipe passing through inside of the outer panel and the inner panel and connecting the inlet plate and the inner connection plate. The inlet plate is joined to the outer panel, the inner connection plate is joined to the inner panel, and the inner panel is joined to the outer panel.

A flow path-forming member mounted to a pipe opening end of a filler pipe forms an insertion flow path portion in which a fueling nozzle is inserted, such that the insertion flow path portion communicates with a fuel flow path. An opening end engagement portion is arranged to cover a flow path inner circumferential wall a flow path outer circumferential wall and a peripheral wall of the fuel flow path at the pipe opening end around the fuel flow path and is engaged with the filler pipe at the pipe opening end. The flow path-forming member mounted to and engaged with the filler pipe is fastened to the filler pipe by means of a fastening structure, in the state that a pipe outer circumferential wall of the filler pipe is covered by an outer circumference covering portion that is provided from the opening end engagement portion to a downstream side of the fuel flow path. This configuration enhances the effectiveness of preventing the flow path-forming member that forms the insertion flow path portion for the fueling nozzle from being unintentionally detached.

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.

A filler head for a fuel filler pipe that includes a housing and a flow guide configured in one piece from metal.

An object is to provide a fuel supply system having a filler neck formed easily with high accuracy. A fuel supply system is configured to supply fuel ejected from a fuel nozzle to a fuel tank. The fuel supply system comprises a filler neck including a resin filler neck body and a metal retainer. The filler neck body is formed in a tubular shape and has an opening end arranged to form an opening which the fuel nozzle is inserted through. The retainer is placed to cover at least part of the opening end of the filler neck body and is joined with the filler neck body in at least part of the filler neck body by thermal welding.

A fuel tank apparatus is adapted to conduct fuel toward the fuel tank of a vehicle. The fuel tank fill apparatus includes a fuel-tank filler neck for conducting fuel to the fuel tank and a capless closure assembly the couples to the fuel-tank filler neck in such a way so as to be removed for serviceability.

A fuel tank for a motor vehicle. The fuel tank includes a tank having an external casing having an opening and a forming zone in a region about the opening, the forming zone having a first forming zone region that is deformed in comparison to a shape of the external casing surrounding the forming zone and a second forming zone region on a periphery of the opening that is deformed greater than the deformation in the first forming zone region. The fuel tank also includes a filler neck for filling the tank, the filler neck leading into an opening of the external casing and being welded to the external casing by way of a weld seam that is accessible from outside the tank, the filler neck in the region of the opening being deformed greater than the deformation than the deformation of the second forming zone region.
