<P>PROBLEM TO BE SOLVED: To provide a torque damper for a hydraulic power transmission in which each spring group is though constituted of a plurality of linear coil springs, and each coil spring is prevented from contact with a cylindrical housing, and which has a simple structure capable of stabilizing torque buffering characteristics. <P>SOLUTION: In the torque damper for the hydraulic power transmission in which a plurality of spring groups 32, 33 composed of a plurality of linear coil springs 40a to 40d is arranged in a cylindrical housing 31 arranged continuously to a clutch piston 21, and a driving spring seat 36b and a driven spring seat 37c of a driving spring seat member 36 and a driven spring seat member 37 each connected to a clutch piston 21 and a turbine impeller 3 are interposed between opposed ends of the adjacent spring groups 32, 33, between adjacent coil springs 40a to 40d among respective spring groups 32, 33, a support unit 39 is interposed which can be rolled on the inner circumferential surface of the cylindrical housing 31 while supporting ends of these coil springs. <P>COPYRIGHT: (C)2012,JPO&INPIT |
