Abstract

Provided is a torsional oscillation damping device with which space for a mass that moves in a reciprocating manner can be maintained and the oscillation damping effect can be improved. This torsional oscillation damping device (1) wherein a mass (3) is attached to a rotating body (2) by means of two support pins (5R 5L) is equipped with: two first hollow parts (4) which are formed in the rotating body (2) at positions corresponding to the support pins (5R 5L) and into which the support pins (5R 5L) are inserted; and two second hollow parts (7) which are formed in the mass (3) at positions opposing the first hollow parts (4) and into which the support pins (5R 5L) are inserted. The portions of the inner circumferential edges of the first hollow parts (4) which are to the outside in the radial direction of the rotating body (2) are guide surfaces (6R 6L) and the portions of the inner circumferential edges of the second hollow parts (7) which are to the inside in the radial direction of the rotating body (2) are attachment surfaces (8R 8L). The guide surfaces (6R 6L) and the attachment surfaces (8R 8L) are formed as concave curved surfaces with the distance D between the centers of curvature O of the guide surfaces (6R 6L) being shorter than the distance D between the centers of curvature O of the attachment surfaces (8R 8L).
