Claims

[Claims for Utility Model Registration] (1) Elastic supports such as air springs, hollow anti-vibration rubber, and metal coil springs, the upper pressure receiving plate of the elastic supports attached to the equipment to be vibration-isolated, and the anti-vibration target. A container having an open top end and having vertically opposing horizontal surfaces on the inner surface is fixed to the lower pressure receiving plate or the upper pressure receiving plate in the space formed between the lower pressure receiving plates of the elastic support attached to the equipment installation surface. , a movable member having horizontal upper and lower surfaces and having a hollow part opened at least at the upper end in the vertical direction is incorporated so as to be movable in the horizontal direction while maintaining an appropriate gap between it and the opposing surface inside the container. The rod, which is attached so that its movement is restricted according to the relative displacement between the upper pressure receiving plate and the lower pressure receiving plate of the support body, is moved in the vertical direction while maintaining an appropriate gap between it and the inner surface of the hollow part of the moving member. A vibration isolating device comprising a damping mechanism which is movably inserted and contains a viscous fluid inside a container and a hollow part of a moving member. (2) The upper end of the rod of the damping mechanism is attached to the upper or lower pressure receiving plate of the elastic support with an appropriate gap in the horizontal and vertical directions via the mounting member fixed to the upper pressure receiving plate or the lower pressure receiving plate, and the rod is attached to the movable member. The vibration isolating device according to claim 1, which is supported by an elastic body such as a spring or rubber.
