PURPOSE:To improve durability while having low dynamic spring high damping characteristics. CONSTITUTION:A liquid chamber space 21 of an elastic body block 20 to be interposed between an outer tube 10 and an inner tube 30 is sectioned into two chambers by an elastic wall 40, and the inner end 44 is fitted into a fitting groove of an elastic wall attaching part 24, and the outer end 46 is pinched between respective ends of two liquid chamber covers 50 for covering the opening part of the liquid chamber space 21. When the block is pressed into the outer tube 10 in this state, the contact part with the elastic body block 20 on the periphery of the elastic wall 40 can be moved even if the elastic wall 40 is elastically deformed by liquid pressure. Thereby, rising of inside pressure is restrained, and stress concentration is alleviated, thereby, low dynamic spring/ high damping characteristic are provided, and durability is improved. |
