PURPOSE:To obtain vibration proofing effect based on flow of fluid by connecting an internal cylinder fitting with an external cylinder fitting through a cylindrical rubber elastic body, and forming a fluid chamber which seals incompressible fluid between the internal cylinder fitting and the external cylinder fitting. CONSTITUTION:An external cylinder fitting 14 is disposed in a diametrical direction outwards from an internal cylinder fitting 12 at prescribed intervals in a bush assembly unit 10, and the fittings are elastically connected with each other by a rubber elastic body provided between the fittings 12 and 14. A ring-shaped space 26 which is connected in the circumferential direction and extends between the fitting 12 and a metallic sleeve 22 is formed in an integrated vulcanining-forming article 24. A metallic ring 20 is positioned in the space 26, and a protruding rubber 30 is formed on the external surface of the ring 20 by an elastic body 16 for integrated cure-bonding. Besides, the fitting 14 is inserted into the forming article 24 from the outside, and is engaged with the circumferential surface of the sleeve 22. By the installation of the fitting 14, an opening in a protruding part 28 of the sleeve 22 is fluid tightly closed to form a fluid chamber 34. Prescribed incompressible fluid is poured and charge into the fluid chamber 34. |
