VEHICLE WHEEL DISC

WIPO Patent Application WO/2010/050582

A1

Disclosed is a vehicle wheel disc in which the selectable range of wheel specifications is broadened as a result of a reduction in the degree of outward protrusion from the curved portion of the perimeter edge of decorative holes in the axial direction of the wheel, in which the wheel disc durability is ensured, in which the number and the arrangement of spoke portions and hub-fastening bolt holes do not restrict each other, in which the hub nut fastening operation is simple, and in which the molding of the wheel disc is simple. Spoke portions (13) of the wheel disc comprise a spoke bottom wall (13a), and spoke side portions (13b) that include spoke side walls (13b1) that extend upward in the axial direction of the wheel from the spoke bottom wall (13a) and spoke reinforcing plates (13b2) that curve from the axial direction of the wheel in the circumferential direction of the wheel from an end portion of the spoke side walls (13b1) in the axial direction of the wheel and extend in the circumferential direction of the wheel. Inner-side end portions of the pair of spoke side portions (13b) in the radial direction of the wheel disposed on either side of decorative holes (15) in the circumferential direction of the wheel are linked by flat connection walls (18) in the circumferential direction of the wheel.
