Claims

[Scope of utility model registration request]

The main liquid chamber has a cylindrical thick rubber elastic wall as its chamber wall, and the main liquid chamber is divided by a partition plate below and communicated with through a throttle hole, and deforms freely according to changes in internal pressure. In a liquid-filled vibration isolator equipped with a sub-liquid chamber consisting of a chamber wall, the thick rubber elastic wall is formed into a truncated cone shape whose diameter narrows upward, and the center of the upper end is set from the center of the lower end. The wall length of the portion of the thick rubber elastic wall that is located along the direction in which the load of the vibrator acts is set to be equal to that of the other portion of the thick rubber elastic wall, so as to support the vibrator at the center position of the upper end by being eccentrically positioned. A liquid-filled vibration isolator characterized by being longer.
