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 a torque fluctuation absorbing device that includes a clutch connecting the transmission side and a hysteresis mechanism interposed between the drive plate and the flywheel, the clutch can rotate relative to the clutch hub and the clutch hub. A damper spring is interposed between the clutch hub and the clutch plate to elastically restrict their relative rotation, and a fan-shaped damper spring is formed on the drive plate side. and a notch formed on the flywheel side, which is fitted into the notch and abuts each end of the flywheel in the circumferential direction of the notch with relative rotation within a set angle range. A torque fluctuation absorbing device characterized by being provided with a fan-shaped engagement piece that transmits rotational torque from a drive shaft.
