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.

Multi-disc clutches are known which usually have a first clutch pack consisting of steel discs and a second clutch pack consisting of friction discs. A disc for a multi-disc clutch is proposed, which has a disc body. The disc body is in a form of an annular disc, and has a driver contour on its inner circumference and/or outer circumference for mounting the disc in a rotationally fixed manner. The disc body is formed by edgewise rolling on the inner circumference thereof.

This disc rotor has a hat portion having a cylindrical portion and a sliding plate portion having an insertion hole into which the cylindrical portion is inserted, being connected together with the hat portion in a state in which the cylindrical portion protrudes from the insertion hole. The coupling is achieved by pinching an inner peripheral edge of the sliding plate portion between a first portion and a second portion that are formed in the cylindrical portion. The second portion is formed by plastically deforming an outer peripheral side of the cylindrical portion toward the first portion.
