To provide a seismic isolator, improved in capability of absorbing the energy of an earthquake, and easily manufactured and constructed at a low price by disposing a damping mechanism formed of a curved member and an isolator between an upper structure and a lower structure.
In this seismic isolator, the isolator 1 and both end parts 8, 9 of two or more curved members 7 formed of elasto-plastic material constituting a damping mechanism are disposed between an upper structure 2 and a lower structure 3, and fixed to the upper structure 2 and the lower structure 3. The curved member 7 is formed to draw a circle like a lantern by combination of two or more members or two or more sets of a pair of two curved members opposite to each other symmetrically, and disposed in the periphery of the isolator 1. Thus, the curved member 7 is plastically deformed to absorb the energy of an earthquake.
