Abstract
The present device includes a mass body, a centrifugal element and a plurality of conversion mechanisms. The mass body is disposed to be rotatable with the rotor and be rotatable relative to the rotor. The centrifugal element is disposed to receive a centrifugal force to be generated by rotation of at least one of the rotor and the mass body. Each of the plurality of conversion mechanisms is configured to convert the centrifugal force into a circumferential force when a relative displacement is produced between the rotor and the mass body in a rotational direction. The circumferential force is directed to reduce the relative displacement. The respective plurality of conversion mechanisms are disposed at intervals in a circumferential direction.
