PURPOSE:To make it possible to effectively damp vibration which is axially exerted, by axially dividing a fluid chamber between an inner cylinder hardware and an outer cylinder with the use of a partition hardware formed therein an orifice. CONSTITUTION:A pair of ring-like resilient members 12 are disposed to form a cylindrical fluid storage space between an inner cylinder hardware 10 and an outer cylinder hardware 18. An orifice member 16 is disposed between both hardwares 10, 18 to axially section the fluid storage space into two fluid chambers 14, 14. This orifice member is formed therein a circumferentially extending communication passage 44 communicating between the two fluid chambers, for exerting a resistance to fluid flowing between both fluid chambers 14, 14 during axial relative displacement of both hardwares 10, 18. |
