<P>PROBLEM TO BE SOLVED: To provide a torsional damper that is reduced in part weight with respect to a sensing mechanism when attaching the sensing mechanism to the inner-mass type torsional damper and achieved in space saving, does not cause breakage and fall-down by resonance with an engine, and does not interfere with a mass body. <P>SOLUTION: The torsional damper includes: a hub having a pulley formed with a pulley groove wound with an endless belt; the mass body arranged at the internal peripheral side of the pulley; and a rubber elastomer connected with the hub and the mass body. The torsional damper also has sensing magnetic rubber having a prescribed circumferential magnetization pattern, and the magnetic rubber is attached to the axial end face or the external periphery of the pulley in the hub. <P>COPYRIGHT: (C)2012,JPO&INPIT |
