Claims

[Claims for Utility Model Registration] (1) A plurality of window holes for arranging torsion springs are formed in each of a pair of input side plates and an output side plate between the side plates, and a torsion spring is installed in each window hole of the output side plate. At least two springs are arranged in series, the torsion springs connect the side plate and the output plate so as to transmit torque, and the torsion springs are moved in the circumferential direction between the two torsion springs in series in each window hole. In the damper disk provided with a floating body, a portion of the output side plate facing the outer circumferential surface of the float body is cut out, and the float body is provided between the outer circumferential surface of the float body and one of the input side plates. A damper disk characterized by having a ball interposed therein that guides the disk so as to be movable in the circumferential direction. (2) A side plate with which the ball is pressed,
The damper disk according to claim 1, which is a registered utility model, and has an arcuate groove that guides the balls in the circumferential direction and prevents them from falling off.
