Abstract: A torque fluctuation inhibiting device includes plural centrifugal elements movable in a radial direction when receiving a centrifugal force generated in rotation of a rotor and a mass body. Each centrifugal element receives a rotational moment of inertia about an axis arranged in parallel to a rotational axis of the rotor when receiving the centrifugal force. When a relative displacement is produced between the rotor and the mass body in a rotational direction due to the centrifugal force acting on each centrifugal element, each cam mechanism converts the centrifugal force into a circumferential force directed to reduce the relative displacement. Support portions are provided on either the rotor or the mass body, and each makes contact with part of each centrifugal element when each centrifugal element receives the rotational moment of inertia. Each support portion supports each centrifugal element such that each centrifugal element is movable in the radial direction.
