PROBLEM TO BE SOLVED: To provide a fluid-sealed damping device capable of advantageously developing an excellent damping effect by a structure easily manufacturable and having excellent durability. SOLUTION: A pressure receiving chamber 32 and an equilibrium chamber 34 are formed between a first mounting member 10 and a second mounting member 12 connected to each other through a body rubber elastic body 14 on both sides of a partition member 30. An orifice passage 50 allowing the pressure receiving chamber 32 to communicate with the equilibrium chamber 34 is formed of a tubular part 38 formed of a rubber elastic body which is formed integrally with the partition member 30. A projection 40 projecting in the direction crossing the axial direction is formed integrally with one end of the tubular part 38 positioned in the pressure receiving chamber 32. A narrowed part 52 is formed between the end surface of the projection 40 and the inner wall surface of the pressure receiving chamber 32. COPYRIGHT: (C)2008,JPO&INPIT |
