Claims (1)

[Scope of utility model registration request] A liquid chamber is formed with a variable volume between an elastic body such as thick rubber extended at the opening end of the cylindrical metal fitting and a flexible thin film extended leaving an air chamber at the end of the lid. A vibration-proof mount in which the liquid chamber is separated by an elastic partition plate interposed between the elastic body and the thin film into two small liquid chambers communicating through an orifice provided on the outer periphery of the partition plate, A hole is bored in the center of the partition plate, a core member is passed through the hole across both of the small liquid chambers, and a flat plate having an outer diameter smaller than that of the partition plate is attached to each end of the core member at a distance from the partition plate. A vibrating member fixed in parallel with each other is provided to be movable in the axial direction within the inner cylindrical fitting with metal springs interposed between the flat plates and the partition, and at least one of the vibrating members A liquid-filled anti-vibration mount characterized in that a flat plate has a gap around its outer periphery to further divide the one small liquid chamber into two liquid chambers.
