Abstract

A torque fluctuation inhibiting device includes a mass body, a centrifugal element and a cam mechanism. The mass body is disposed to be rotatable with a rotor and be rotatable relatively to the rotor. The centrifugal element is disposed to receive a centrifugal force to be generated by rotation of the rotor and the mass body. When a relative displacement is produced between the rotor and the mass body in a rotational direction, the cam mechanism converts the centrifugal force that acts on the centrifugal element into a circumferential force directed to reduce the relative displacement. Additionally, when the torque fluctuations inputted to the rotor have a predetermined magnitude or greater, the cam mechanism makes the mass body freely rotate with respect to the rotor.
