PURPOSE: To realize a low dynamic spring while preventing injury of an elastic body and improving durability. CONSTITUTION: An intermediate cylinder 18 is arranged in an outer cylinder 16, and an inner cylinder metal fitting 12 is arranged in the intermediate cylinder 18 through a main body rubber 14. A pressure receiving liquid chamber 28 and a liquid sub-chamber 30 are provided in the outer cylinder 16, and these are communicated to each other through passages 34. A guide rail part 14B rectilinearly formed in the lengthwise direction as X-direction is provided in the center part of the main body rubber 14, and a stopper member is arranged in the pressure receiving liquid chamber 28. A fitting groove 41 is formed on the stopper member, and the fitting groove 41 is slidably fitted to the guide rail part 14B of the main body rubber 14. Consequently, even if the main body rubber 14 is struck with the stopper member by displacement in X-direction, the stopper member is slid to escape, so as to prevent injury of the main body rubber 14. |
