A filler pipe includes a nozzle guide that is mounted on an inlet part of the filler pipe and holds a nozzle end part of a fueling gun. The nozzle guide includes a nozzle guide mounting part, which is mounted on the inlet part of the filler pipe, a nozzle guide holding part, which is positioned in a distal end of the nozzle guide, and holds the nozzle end part of the fueling gun, and a nozzle guide connecting part that connects the nozzle guide mounting part and the nozzle guide holding part with each other. The nozzle guide holding part has a plurality of projecting parts that are able to abut on an outer surface of a nozzle of the fueling gun. The nozzle guide is mounted on the inlet part of the filler pipe, at the nozzle guide mounting part, by swaging or spot welding.

Filler pipe

Each spoke portion () includes a center valley portion (), and spoke projecting threads () formed on both sides of the center valley portion (). Each of the spoke projecting threads () includes an inclined surface portion (), which protrudes outward in a spoke widthwise direction from a top () and inclines downward to a wheel axially back side. The inclined surface portion () is formed so that a length thereof in a range of from the top () to an outer end of the inclined surface portion () in the spoke widthwise direction becomes larger toward a spoke distal end side, and that an average downward inclination angle thereof becomes smaller toward the spoke distal end side. With this configuration, it is possible to increase rigidity of the spoke portion with good balance while avoiding interference with a braking device.

Automobile wheel

Each spoke portion includes spoke projecting threads on both sides thereof, and a reinforcing plate portion is formed so as to protrude from a side edge of each of the spoke projecting threads outward in a spoke widthwise direction. The reinforcing plate portion is formed continuously with an inter-spoke plate portion extended from a fitting portion of a disc flange portion to a wheel radially inner side, and forms an integral plate surface with the inter-spoke plate portion. With this configuration, it is possible to reduce imbalance of rigidity of the spoke portion in a radial direction, and to increase rigidity of an automobile wheel.

An automobile wheel is provided with a spoke section and a disk flange section. The spoke section is provided with a central groove section and raised side section disposed on either side of the central groove section. The raised side sections are provided with a peak side section that protrudes to the front and a flange section that extends from the side edge of the peak side section to the back. Meanwhile, the disk flange section is provided with a connector section and front edge sections that curve radially inward from the front edge of the connector section. The front edge sections are depressed toward the back relative to the peak side section of the raised side section. This automobile wheel, by means of the synergy between the shape effects of the spoke section and the disk flange section, improves strength and rigidity for withstanding radial loads and bending/torsional loads.

In an automobile wheel, a disc flange of a wheel disc includes bent surface-side edge portions each having an arcuate shape and arranged concentrically with each other, and the bent surface-side edge portions extend from the surface-side end edge of a fitted straight annular portion to be bent radially inward and are dented to a back side of the outer end portions of the lateral edge portions of spokes. The thus configured automobile wheel can exhibit high strength and rigidity against a radial load, a bending load, and a torsional load because of the shape of the bent surface-side edge portions, thereby suppressing deformation of the disc flange caused while an automobile is running. Thus, it is possible to mitigate a stress concentration on a joined portion between the wheel disc and a wheel rim.
