Claims

[Scope of Claim for Utility Model Registration] (1) A seismic isolation structure characterized by having a seismic isolation mechanism consisting of a combination of a ball and a spherical saucer between a foundation or foundation structure and an object to be seismically isolated. (2) The seismic isolation structure according to claim (1), wherein the spherical saucer is provided on at least one of the foundation, the foundation structure itself, or the seismically isolated object itself.
