Claims

[Claims for Utility Model Registration] (1) A hub flange is integrally provided on the outer periphery of the hub, a clutch plate and a retaining plate are provided on both sides of the hub flange, and hysteresis occurs between the retaining plate and the hub flange. In the clutch disk assembly including the mechanism, the hysteresis generating mechanism includes a friction plate on the hub flange side having a pawl that fits into a hole in the retaining plate, and a friction plate between the friction plate and the retaining plate. a spring member to be contracted; a friction washer disposed between the friction plate and the hub flange; and one of the friction washers, the friction washer being coupled to the hub or the friction plate. 1. A clutch disk assembly characterized by comprising a friction washer rotation preventing means for causing only the surface thereof to come into sliding contact with the surface opposite the surface. (2) The clutch disc assembly according to claim 1, wherein the rotation preventing means is a protrusion of a friction plate that fits into a hole in a friction washer. (3) The clutch disk according to claim 1, wherein the rotation preventing means is a hole shaped along the outer periphery of the hub, which is notched in the center of the outer periphery of the hub and the friction washer.
