Claims

[Scope of utility model registration request]

Between the foundation and the supported body, there is a restoring type seismic isolation support made of an air spring and laminated rubber that can be displaced in the horizontal and vertical directions and are connected in series, and the horizontal displacement is restrained. A sliding type consisting of an air spring that is displaceable only in the vertical direction, is fixed to one of the facing surfaces of the foundation and the supported body, and is slidable in the horizontal direction on the other facing surface. A three-dimensional seismic isolation device characterized in that a suitable number of seismic isolation supports are arranged in combination.
