Claims

[Scope of utility model registration request]

A first fluid chamber made of a thick rubber elastic wall, and a second fluid chamber made of a thin rubber elastic wall and separated from the first fluid chamber by a partition plate having a throttle hole in the center. A liquid-filled vibration damper is provided, wherein the volumes of the two fluid chambers change relative to each other due to the vibration of the supported body supported by the thick rubber elastic wall, so that the sealed liquid flows through the throttle hole. In the device, a third fluid chamber is provided in the partition plate, and a small hole is formed in the partition plate to connect the third fluid chamber to the first and second fluid chambers.
The third fluid chamber is connected to the fluid chamber on the first fluid chamber side and the second fluid chamber by a thin rubber elastic sheet.
A liquid-filled vibration isolator characterized in that the liquid-filled vibration isolator is divided into a fluid chamber on the fluid chamber side.
