Patent ID: 8491062

Claim:
A vehicle wheel including a disk press-formed from a plate, the disk comprising: a hub coupling portion; a plurality of spokes each extending outwardly in a radial direction of a wheel from the hub coupling portion; a vent window located between adjacent spokes; and a radially outer disk located at a radially outer end of the wheel and connecting radially outer ends of the adjacent spokes along a circumferential direction of the wheel, wherein each of the spokes includes a spoke bottom wall having a width extending along the circumferential direction of the wheel and a pair of spoke side walls rising from opposite circumferential ends of the spoke bottom wall in an axial direction of the wheel, wherein each of the spokes is located outside the hub coupling portion and the radially outer disk in the axial direction of the wheel, wherein each of the spokes includes a waved portion located at only a portion of each of the spokes in the radial direction of the wheel, the waved portion extending in a direction perpendicular to the radial direction of the wheel at each of the spokes and decreasing a bending rigidity of each of the spokes in the radial direction of the wheel by decreasing a height of each of the pair of spoke side walls in the axial direction of the wheel; and wherein the waved portion is formed by displacing the spoke bottom wall in the axial direction of the wheel and in a direction decreasing a height of each of the pair of spoke side walls in the axial direction of the wheel.
