AUTOMOTIVE WHEEL DISK

WIPO Patent Application WO/2011/055839

A1

Provided is an automotive wheel disk such that even if decorative windows are enlarged to improve ornamental characteristics, the strength and the stiffness of the disk can be secured without increasing the material thickness of a disk compared to conventional disks. A hat section (15) comprises a top section (15a) which continuously extends in the disk circumferential direction; an inner circumferential curved section (15d) which, in an area inward of the inner circumference of the top section (15a), bends toward the inside in the disk axial direction and extends continuously in the disk circumferential direction; and an outer circumferential curved section (15c) which, in an area outward of the outer circumference of the top section (15a), bends toward the inside in the disk axial direction and extends continuously in the disk circumferential direction. When seen from the disk axial direction, the shape of the hat section (15), which comprises the top section (15a) and the inner circumferential curved section (15d), both sections being continuous in the disk circumferential direction, is undulating.
