Abstract
A torsional vibration damper in which collision noise resulting from collision of a rolling member against a rotary member is reduced. The torsional vibration damper comprises a restriction mechanism that establishes a restriction force in a direction to restrict the relative rotation between the rotary member and the inertia body, when the rolling member centrifugally pushed onto a raceway surface is pushed radially inwardly by the raceway surface toward a radially inner limit position of a guide section.
