PROBLEM TO BE SOLVED: To provide a partition plate capable of preventing the loss of membrane rubber characteristics. SOLUTION: In a vibration isolator 1 including an elastic body 15 for connecting a vibration generating part and first and second attaching parts together, a liquid chamber in which liquid is injected, a partition plate 17 for dividing this liquid chamber into a pressure receiving liquid chamber 19 expanded/contracted by the deformation of the elastic body and a sub-liquid chamber 20 adjacent to this room 19 and a limit passage 21, the partition plate 17 is composed of membrane rubber 16 extended between the pressure receiving liquid chamber 19 and the sub-liquid chamber 20 and a polymer material partition wall 27 integrally formed to support the membrane rubber 16. A flange part 29 projecting in a diameter direction is provided in the outer periphery of the membrane rubber 16, this flange part 29 is buried in the partition wall 27 and a butless part 30 is provided from the outer periphery of the membrane rubber to the flange part 29. |
