Abstract: The present device includes an inertia ring, a plurality of centrifugal elements, a plurality of cam mechanisms and a plurality of restriction mechanisms. The inertia ring is disposed to be rotatable with a hub flange and be rotatable relatively to the hub flange. Each centrifugal element is disposed to receive a centrifugal force generated by rotation of the hub flange and the inertia ring. When a relative displacement is produced between the hub flange and the inertia ring in a rotational direction while the centrifugal force is acting on each centrifugal element, each cam mechanism converts the centrifugal force into a circumferential force directed to reduce the relative displacement. Each restriction mechanism allows actuation of each centrifugal element by each cam mechanism, and restricts radial movement of each centrifugal element.
