Claims

[Scope of utility model registration request]

A gap is provided inside the mount rubber fixed between the substrate on the supporting body side and the substrate on the side of the supported body, and a partition plate with an aperture is attached to either of the substrate sides, and a fluid is supplied to the gap side of the partition plate. In a fluid-filled vibration isolator, the fluid-filled vibration isolator comprises a chamber, and a sub-chamber partitioned by a diaphragm on the other side of the partition plate, and the fluid chamber and at least a part of the sub-chamber are filled with fluid. , a mass elastically supported by an elastic body is provided with one side of the mass facing a fluid chamber and the other side facing a fluid chamber other than the fluid chamber or the atmosphere; A fluid-filled vibration isolator comprising a dynamic vibration absorber made of an elastic body and having a resonance point when high frequency vibration is input.
