Patent ID: 8646851

Claim:
A vehicle wheel comprising: (a) a rim having a drop portion which is a smallest-diameter portion of the rim, and a radially inner surface; and (b) a disk having a hub coupling portion, a plurality of spokes extending outwardly in a radial direction of the wheel from the hub coupling portion and a disk flange located at a radially outer end portion of the disk of the wheel and connecting radially outer end portions of the plurality of spokes along a circumferential direction of the wheel, the disk including a vent window formed between each pair of adjacent spokes of the plurality of spokes, the drop portion and the disk flange being connected to each other, wherein the hub coupling portion has an axially inner surface in an axial direction of the wheel and the axially inner surface of the hub coupling portion is positioned between an axially outer end and an axially inner end of the disk flange in the axial direction of the wheel; wherein the spoke has a bottom wall portion extending in the circumferential direction of the wheel, a pair of side wall portions each rising in the axial direction of the wheel from each of circumferentially opposite ends of the bottom wall portion and a brim portion extending in the circumferential direction of the wheel from each of the pair of side wall portions; wherein each vent window is partially bounded by an axially outermost portion of the brim portion of a respective spoke; wherein the disk flange has a non-contact portion non-contacting the radially inner surface of the rim, at a radially outer extension of a width center line of each of the plurality of spokes; wherein the non-contact portion is constructed from a cut portion formed at the disk flange and located at the radially outer extension of the width center line of each of the plurality of spokes; and wherein the cut portion has an open end positioned at a circumferential extension of the axially inner end of the disk flange in the axial direction of the wheel.
