Abstract
A torque fluctuation inhibiting device includes a mass body. The mass body disposed to be rotatable with a rotor and be rotatable relatively to the rotor. Each of a plurality of centrifugal elements is radially movable by a centrifugal force that acts thereon in 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 while the centrifugal force is acting on the each of the plurality of centrifugal elements, each of a plurality of cam mechanisms converts the centrifugal force into a circumferential force directed to reduce the relative displacement. A plurality of restriction members allow the plurality of centrifugal elements to move in actuation of the plurality of cam mechanisms, and restrict the plurality of centrifugal elements from moving radially inward in non-actuation of the plurality of cam mechanisms.
