PROBLEM TO BE SOLVED: To improve control stability while reducing rigidity. SOLUTION: An elastic body 16 formed with a pair of opening recessed parts 16C is arranged between an inner cylinder metal fittings 14 and an outer cylinder metal fitting 12, and intermediate cylinder metal fittings 18 are arranged on the outer circumference side of the elastic body 16. A sealing metal fitting 20 is fitted to the outer circumference of the intermediate cylinder metal fittings 18, the open recessed parts 16c are sealed with the sealing metal fitting 20, and hence liquid chambers 26A, 26B are formed. A recessed part 12A is formed on the inner circumferential face side of the outer cylinder metal fitting 12, and a slider 34 is movably arranged therein. A coil spring 36 is arranged between a left inner wall surface or a right wall surface of the recess part 12A and a slider 34. A groove part 34A is formed on the inner circumferential face side of the slider 34, and through holes 20A are formed on the sealing metal fitting 20. Consequently, orifices 30 are formed between the groove part 34A and the sealing metal fitting 20, and the liquid chambers 26A, 26B are communicated together via the through holes 20A. |
