PROBLEM TO BE SOLVED: To form a stopper mechanism, easily adjusting a stopper clearance, with sufficient strength, by positioning the first/second stopper parts, integrally formed in an intermediate cylinder member, in both sides interposing a support shaft member. SOLUTION: The first stopper part 36 is integrally formed in a peripheral direction extension part 34. The first stopper part 36, in the first pocket part 22, is positioned to be protruded toward an inner cylinder metal fixture 12 from a side of an intermediate cylinder member 18. Cushioning rubbers 38, 40 of prescribed thickness are respectively integrally formed with a rubber elastic unit 6 in an opposed surface of the first stopper part 36 and the inner cylinder metal fixture 12. The second stopper part 56 is integrally formed in a bridged part 52. The second stopper part 56, in a slit 26, is positioned to protrude toward the inner cylinder metal fixture 12 from a side of the intermediate cylinder member 18. A cushioning rubber 58 of prescribed thickness is integrally formed with a rubber elastic unit 16 in an opposed surface relating to the second stopper part 56 of the inner cylinder metal fixture 12. |
