Claims

[Scope of Claim for Utility Model Registration] 1. In a clutch in which the fastening force of the friction plate is applied by a piston, a disc spring that urges the piston toward the release side of the fastening force is provided, and a rotation prevention member that prevents rotation of the disc spring is provided. A return mechanism member for a clutch piston. 2. The friction plate has an outer plate on the non-rotating side, and the case member into which the outer plate is serrated and the piston is incorporated has an escape groove for serration processing, and the outer periphery is inserted into the escape groove. Claim 1, wherein the disc spring formed in a shape corresponding to the serrations is disposed, and the rotation prevention member is a set plate that engages with the outer periphery of the disc spring and is fitted with the serrations to the case member. Return mechanism member for the clutch piston described.
