<p>PROBLEM TO BE SOLVED: To provide a torsional vibration attenuation device capable of reducing spring rigidity of an elastic member in a high torque area having a large torsional angle, and capable of improving attenuation performance of torsional vibration.SOLUTION: In a torsional vibration attenuation device, one end part 14a of a coil spring 14 and another end part 14b thereof are arranged in disc plates 12, 13 and a hub plate 11 so as to be displaced in a rotational axis direction of the disc plates 12, 13, and as the hub plate 11 is twisted on a positive side (an acceleration side) with respect to the disc plates 12, 13, the one end part 14a of the coil spring 14 moves in the rotational axis direction.</p> |
