PROBLEM TO BE SOLVED: To provide a torsional vibration reduction device of high vibration control performance by reducing sliding friction between a rolling elements and a member connecting the rolling elements.SOLUTION: In a torsional vibration reduction device in which a plurality of guide holes 2 are formed on a rotor 1 rotated by receiving torque, at prescribed intervals in a circumferential direction of the rotor 1, rolling elements 3 reciprocated in a circumferential direction of the rotor 1 by fluctuation of the torque in a state of rotating the rotor 1, are accommodated in the guide holes 2, and the rolling elements 3 are connected by connecting members 5, the connecting members 5 include accommodating portions 7 holding the rolling elements 3 from outer peripheral faces 3a, 3e, 3f side, and at least two contact portions 7b, 7c point-contacted or line-contacted with the outer peripheral faces 3a, 3e, 3f of the rolling elements 3 in the reciprocating direction of the rolling elements 3, are formed on inner faces of the accommodating portions 7.SELECTED DRAWING: Figure 1 |
