Abstract
The present invention is intended to provide a seismic isolation device which, regardless of a load to be supported, is capable of reducing acceleration through lengthening a natural period of an upper structure, with excellent vibration energy absorbing capacity by obtaining a properly preferable frictional force as well as a returning characteristic, and others.
