ABSTRACT:
An anti-vibration apparatus for reducing seismic acceleration is disclosed wherein X-axis direction linear motion means are horizontally displaceably mounted on X-axis direction rails installed on a foundation, and mounted on the X-axis direction linear motion means are Y-axis direction rails through Y-axis direction linear motion means or directly, and X- and Y-axis direction tension springs are disposed between the foundation and the X-axis direction rails and between the X-axis direction linear motion means and the machinery mounting platform, whereby the X- and Y-axis direction linear motion means are adapted to support transverse upward as well as downward loads together with the X- and Y-axis direction rails. The machinery mounting platform may additionally pivotally carry thereon another machinery mounting platform through articulated lever mechanisms using the former platform as a support frame.
