Claims

[Scope of utility model registration request]

An intermediate annular body is arranged between a pair of input-side side plates, an output-side hub is arranged on the inner peripheral side of the intermediate annular body, and the flange of the hub and the intermediate annular body are connected through a first stage torsion spring with a small spring constant. In a damper disk in which an intermediate annular body and a side plate are connected in a torque-transmissible manner via a second-stage torsion spring having a large spring constant, a pair of left and right thick-walled The annular intermediate plates are overlapped and connected by rivets, and a window hole for arranging the second stage torsion spring is formed on the outer peripheral side of the intermediate plate, and an expansion hole for storing the first stage torsion spring is formed on the inner peripheral end of the intermediate plate. At the same time, a stopper mechanism for direct torque connection consisting of an uneven part is formed between the flange of the hub and a friction member is provided between the widened part and the side plate and between the widened part and the flange of the hub. Damper disc placed.
