Abstract
A dynamic damper device for inhibiting torque fluctuations in a rotor to which a torque is inputted includes a mass body and a magnetic damper mechanism. The mass body is disposed to be rotatable with the rotor and be rotatable relatively to the rotor. The magnetic damper mechanism includes at least a pair of magnets disposed in the rotor and the mass body. The magnetic damper mechanism couples the rotor and the mass body in a rotational direction by a magnetism of the pair of magnets.
