Further, the piston rod 10 and a seal member 11 which is in sliding contact with the piston rod 10 and seals the open end of the cylinder 8 are provided. A spring 12 is built in the dashpot 7 as a restoring means for returning the piston 9 to a predetermined position in the cylinder 8. Reference numeral 13 is an orifice formed in the piston 9. When the piston 9 moves in the cylinder 8, the orifice 13 causes the working fluid to be replaced and flowed from one chamber in the cylinder 8 to another chamber to generate resistance.

る騒音の発生を抑制できる。According to the structure of the above embodiment, the clutch disc (not shown) is brought into sliding contact with the output member 6 of the flywheel 1,
When the drive torque is transmitted from the drive shaft 2 to the output shaft (not shown) via the flywheel 1 and the clutch disc, the output member 6 and the input member 4 of the flywheel 1 relatively rotate. At this time, the dashpot 7 is connected to the output member 6
And the fluid resistance force in the direction to prevent the relative rotation of the input member 4 and the spring force of the spring 12. Therefore, the driving torque is smoothly transmitted from the input member 4 to the output member 6 via the dashpot 7. In addition, when torque vibration or the like causes torsional vibration in the drive shaft 2 during power transmission, the torsional vibration of the drive shaft 2 causes vibration (relative movement) between the input member 4 and the output member 6 of the flywheel 1. However, since vibration generated between the two is absorbed and damped by the dashpot 7, the transmission of torsional vibration from the drive shaft 2 side to the output shaft side (not shown) is suppressed. Therefore, the torsional vibration of the power transmission system can be reduced, and the generation of noise due to the vibration can be suppressed.

ュポット７のばね１２のばね力で元の位置に復帰する。When the rotation of the drive shaft 2 is stopped and the load acting on the flywheel 1 is released, the output member 6 is returned to its original position by the spring force of the spring 12 of the dashpot 7.

する減衰力にばらつきを生じない。The dashpot 7 is filled with a liquid and a gas therein, but when the drive shaft 2 is rotated, the liquid is located on the outer peripheral side by centrifugal force, while the gas is located on the inner peripheral side. However, it is devised so that gas is not located in the operating range of the piston 9. Therefore, the damping force generated by the dashpot 7 does not vary.

部材４と出力部材６とを連繋すること等が考えられる。In the above embodiment, the spring 12 is incorporated in the dashpot 7. However, the present invention is not limited to this, and the dashpot and the spring that do not include the spring are combined to form the dashpot and the spring. You may make it connect the input member 4 and the output member 6. For example, it is conceivable that a plurality of dash pots and springs that do not include a spring are alternately arranged in the circumferential direction, and that the input member 4 and the output member 6 are connected by these dash pots and springs.

振動の低減及び車両騒音の低減化を図ることができる。As described above, according to the present invention, the damping force (resistance force) varies between the input member fixed to the drive shaft and the output member rotatably engaged with the input member. Since a small number of dashpots are connected to each other, it is possible to reduce variations in damping force due to torsional vibration for each product. Therefore, the torsional vibration on the drive shaft side can be stably damped between the input member and the output member, and the vehicle vibration and the vehicle noise can be more effectively reduced.
