<p>PROBLEM TO BE SOLVED: To provide a torsional vibration damping device capable of changing over a liquid load without special electric control, and effectively damping torsional vibration.SOLUTION: The torsional vibration damping device includes a disc 11 fixed to a rotating shaft, a movable body 13 stored in a recessed part 14 formed in the end face of the disc 11 in a projecting/retracting manner, and an energizing member 16 for energizing the movable body 13 to the outside of the recessed part 14. The movable body 13 has a first pressure receiving face 13a for receiving a pressure from fluid R so that it retracts into the recessed part 14 against the energizing force of the energizing member 16 when the rotating shaft is rotated to one side, and a second pressure receiving face 13b for receiving a pressure from the fluid R in the tangential direction of the rotating shaft when the rotating shaft is rotated to the other side. Inside the recessed part 14, a turning shaft 15 is provided extending in the radial direction of the disc 11. The movable body 13 is turnably supported with the turning shaft 15 as a supporting point.</p> |
