Abstract
A base isolator has four base isolation units placed at four corners between a floor slab and a floor plate. Each base isolation unit has a middle plate, a lower support body which is rotatable in a first direction on the lower side of the middle plate, and an upper support body rotatable in a second direction on the upper side of the middle plate. The upper support body and the lower support body each have mutually eccentric rollers. The middle plates of the four base isolation units are separated from one another so that the plates can be independently displaced or moved.
