Claims

[Scope of utility model registration request]

An inertial body consisting of a drive plate connected to a drive shaft, a flywheel coaxially provided with the drive plate and rotatable relative to the drive plate, and an inertial body that is in pressure contact with the flywheel and connects the engine side and the transformer. In the torque fluctuation absorbing device, the clutch disk is connected to the transmission side, and the hysteresis mechanism is interposed between the drive plate and the flywheel. It is composed of a clutch plate that is rotatably engaged, and a damper spring that is interposed between the clutch hub and the clutch plate and elastically restricts the relative rotation thereof, and is formed on the drive plate side. A fan-shaped notch is formed on the flywheel side, and is inserted into the notch and rotates relative to each end of the notch in the flywheel circumferential direction within a set angle range. A fan-shaped engagement piece that contacts and transmits the rotational torque from the drive shaft, and a concave part and a convex part that are formed on one and the other of the notch and the engagement piece, respectively, and that cushion the impact when the two come into contact. A torque fluctuation absorbing device characterized by being provided with.
