PURPOSE:To simplify the assembly of a bevel metal fitting which contributes to the vibrationproofness in a high frequency region and prevent the complicate structure of the first base plate, etc. CONSTITUTION:The first base plate 1 and the second base plate 3 are connected through a rubber elastic body 5, and a pressure receiving chamber 17 and an equillibrium chamber 18 are formed in partitioning by a partitioning member 9. At the center part of the partitioning member 9, a rubber movable plate 15 is installed, and an orifice passage 14 is formed on the outer periphery. A bevel metal fitting 19 forms an annular shape, and press-fitting-fixed on the outer periphery of the cylindrical part 9a of the partitioning member 9. The bevel metal fitting 19 extends to the outer periphery along the surface crossing at right angle with the vibration input direction, and is set close to the inner wall surface of the pressure receiving chamber 17. |
