Seismic isolator

摘要

A seismic isolator wherein vibrating units 5 arranged in a multiplex manner are formed of suspension members 53 constituting tensile force bearing members, and frames 51 and bases 52 to which both end portions of the suspension members are joined, adjacent vibrating units 5, 5 being joined together by diagonal members 6 of wire rods constituting compressive force bearing members, whereby the area occupied by the seismic isolator decreases.
