<P>PROBLEM TO BE SOLVED: To provide a torque variation absorbing apparatus that greatly ensures the torsion angle while ensuring the torque capacity. <P>SOLUTION: The torque variation absorbing apparatus includes: rotatably-arranged first rotating members 17, 18; a second rotating member 23 that is rotatably and coaxially arranged with respect to the first rotating members; and coil springs 34, 35, and 36 that absorb torque variations occurring between the first rotating members and the second rotating member. The coil springs are composed of three or more types of coil springs arranged on the same circumference. The torsional stiffness when the coil springs are compressed is switched to three or more stages or a continuously variable state. <P>COPYRIGHT: (C)2013,JPO&INPIT |
