Claims

[Claims for Utility Model Registration] (1) A container is fixed to the installation surface of the device to be attenuated or the device to be attenuated, the inner surface of which is formed with a horizontal upper surface and lower surface that face each other in the vertical direction, and whose top end is open. A movable member is formed with an upper surface and a lower surface, and has a hollow part opened at least at the upper end in the vertical direction, and is installed so as to be movable in the horizontal direction while maintaining an appropriate gap between the upper surface and the lower surface inside the container. The rod, which is attached so that its movement is restricted according to the relative displacement between the equipment to be damped and the installation surface of the equipment to be damped, is moved vertically with an appropriate gap maintained between it and the inner surface of the hollow part of the moving member. 1. A damping device, characterized in that the damping device is movably inserted and contains a viscous fluid inside a container and a hollow portion of a moving member. (2) The upper end of the rod is installed with an appropriate gap in the horizontal and vertical directions via a mounting member fixed to the equipment to be damped or to the installation surface of the equipment to be damped, and the rod is attached to the moving member with a spring spring. Alternatively, the damping device according to claim 1, which is a registered utility model, is supported via an elastic body such as rubber.
