Claims

[Scope of utility model registration request]

An inertial body is constituted by a drive plate connected to the drive shaft and a flywheel disposed coaxially with the drive plate and supported on the drive plate so as to be relatively rotatable, and between the drive plate and the flywheel. Torque fluctuation absorption includes a spring mechanism, a damping/torque limit mechanism, and a hysteresis mechanism, and the rotation of the drive shaft is transmitted to the flywheel via the drive plate, the spring mechanism, the damping/torque limit mechanism, and the hysteresis mechanism. In the apparatus, in the drive plate, a side plate forming a surface portion of the drive plate opposite to the flywheel is formed separately from a flywheel main body forming an axially central portion, and the side plate is made of a steel plate;
Furthermore, the torque fluctuation absorbing device is characterized in that the load supporting points on both sides of the side plate are aligned in different positions in the radial direction.
