動を完全に減衰することができることになる。When the torque from the driving side is small, a soft spring constant (low spring constant) by the inner rubber 8 of the damper portion 7 is obtained, so that the vibration generated at the time of low torque input is effectively reduced. This state is the characteristic of the first stage in FIG.
The characteristics of the first stage are obtained within a range where the inner rubber 8 is displaced in the rotation direction and the metal piece 10 of the damper portion 7 comes into contact with the stopper portion 5, and this range is in the rotation direction of the inner rubber 8. Since the displacement amount is large, it can be greatly expanded compared to the conventional one, and therefore, the range where the anti-vibration effect can be obtained can be greatly expanded. The generated vibration can be completely attenuated.

The displacement is limited, and the state is switched from the low spring state by the inner rubber 8 to the high spring state by the outer rubber 9, which is the characteristic of the second stage in FIG. 3, and the overall rigidity is increased by the characteristic of the second stage. Therefore, breakage of the inner rubber 8 can be prevented, and high torque from the driving side can be reliably transmitted to the driven side.

Therefore, the range in which the anti-vibration effect against vibration can be obtained can be greatly expanded, so that the vibration generated at low torque input can be reliably attenuated, and the overall rigidity at high torque input is increased. Can prevent damage to the inner rubber during high torque input.
Durability can be improved, and high torque can be reliably transmitted to the driven side. Further, when switching from the low spring state to the high spring state, the metal piece of the damper part comes into contact with the stopper part via a part of the outer rubber, so that the rising at the time of switching can be made gentle. This has an excellent effect that it is possible to prevent occurrence of a hitting sound at the time of rising.
