Abstract:
A vehicle wheel disc includes a flat plate-shaped hub-mounted part, a cylindrical rim-mounted part, and a hat-shaped part. The hat-shaped part includes a hat top portion, a hat inner peripheral portion, and a hat outer peripheral portion. At a border between the hub-mounted part and the hat inner peripheral portion, a first connecting portion is provided, and at a border between the hat top portion and the hat outer peripheral portion, a second connecting portion is provided. The plate thickness of the hat outer peripheral portion is smaller than the plate thickness of an intermediate portion that is a portion from a border between the first connecting portion and the hat inner peripheral portion to a border between the hat top portion and the second connecting portion in the disc radial direction.
