Claims

[Scope of Claim for Utility Model Registration] (1) A lower pedestal A placed on the floor, and a vibration generating body (equipment, etc. as appropriate) placed facing above the lower pedestal at an appropriate distance from the lower pedestal. This is a vibration damping device applied to a mechanical device having an upper pedestal B on which it is mounted, and in which a suitable vibration isolating member such as an air spring for vibration-isolating the vibration generating body is arranged. Each of the support plates 4 is fixed and erected facing each other with a gap between them, and each friction plate 5 is fixed to either the inner surface of the support plate or the outer surface of the pressing plate described later while being in pressure contact with the opposing inner surface of each support plate. , each vertical pressing plate 11 is configured such that the outer surface of the pressing plate is in pressure contact with the opposing inner surface of each friction plate, and each pressing plate is configured to be able to move slightly in the left and right direction within the opposing support plate. A second elastic body 3, which is made of an elastic member made of a spring-based material and is attached to each pressing body while exerting a pressing force that constantly presses the entire pressing body downward, and an air pressure The first elastic body 2 is made of an adjustable air spring member or the like and is fixedly disposed on the opposing inner surface of each of the pressing plates while exerting a pressing force in the opposing direction of each of the supporting plates. Characteristic vibration damping device. (2) Each of the pressing bodies 4 is formed into a substantially L-shape by a vertical pressing plate 11 and a bottom plate 12 perpendicular to the pressing plate 11, and the second elastic body 3 is disposed on this bottom plate. The vibration damping device according to claim 1, comprising:
