Claims

[Scope of utility model registration request]

A pulley 2, on which a belt connected to an auxiliary machine is hung, is connected to the outer periphery of a hub 1 fitted to the engine crankshaft via a rubber coupling ring 4, which reduces torque fluctuations on the crankshaft side that occur mainly during low-speed rotation. A torque fluctuation absorbing damper that operates so as not to transmit the torque to the belt or auxiliary equipment, characterized by being provided with a centrifugal clutch mechanism 8 that directly connects the hub 1 and the pulley 2 until a required rotational speed range is reached. Fluctuation absorption damper.
