<P>PROBLEM TO BE SOLVED: To prevent the reduction of vibration proof performance by effectively suppressing the accumulation of heat to an elastic body by enhancing the circulation of air in a torsional damper. <P>SOLUTION: The torsional damper has a hub 1, annular mass bodies 22, 32 coaxially arranged in the outer peripheral side of the supporting cylinder part 13 of the hub 1, and damper parts 2, 3 comprising elastic bodies 23, 33 for elastically coupling the hub 1 and the annular mass bodies 22, 32, air circulation cutouts 13a are opened and arranged in the supporting cylinder part 13, and fins 34 extending to the inner peripheral side of the supporting cylinder part 13 and in the rotational direction of the hub 1 are arranged in the air circulation cutouts 13a. <P>COPYRIGHT: (C)2013,JPO&INPIT |
