TORSIONAL VIBRATION REDUCTION DEVICE

摘要

A torsional vibration reduction device that is provided inside of a fluid power transmitting device (1) that has a driving side member (2) that generates a fluid flow, and a driven side member (5) that is driven by the fluid flow, includes a rolling element (29) configured to move in a reciprocating manner according to a variation in torque; a retaining member (20) that has a rolling chamber (28) configured to house the rolling element (29) in a manner that enables the rolling element (29) to move in a reciprocating manner; and a housing (16) configured to shield the rolling element (29) and the rolling chamber (28) from fluid inside of the fluid power transmitting device (1). The retaining member (20) is enclosed and fixed inside the housing (16), and the housing (16) is fixed to the driven side member (5).
