PURPOSE:To attin light weight and reduce machining members while maintaining a damping characteristic. CONSTITUTION:A rubber elastic body 16 with a connecting part 16A extended onto the outer cylinder 12 side from the periphery of an inner cylinder fitting 14 is disposed between the inner cylinder fitting 14 and the outer cylinder 12. A stopper 20 is formed on the inner peripheral surface side of the outer cylinder 12 in such a way as to be opposed to the inne cylinder fitting 14. A liquid chamber 26 is provided in the stopper 20 and the outer cylinder 12 and filled with liquid. A partition wall member 28 is disposed in the liquid chamber 26 so as to divide the liquid chamber 26 into a main liquid chamber 26A and an auxiliary liquid chamber 26B, and an orifice 30 for communicating these chambers is formed on the outer peripheral surface of the partition wall member 28. Accordingly, when vibration is transmitted, the connecting part 16A comes in contact to deform the stopper 20, and pressure change or the like is generated to the liquid in the orifice 30 so as to damp the vibration not only by the deformation of the elastic body 16 but also by the pressure change or the like of the liquid. |
