PROBLEM TO BE SOLVED: To prevent a buckling of an elastic support body easily and certainly without lowering the vibration absorption performance and the elastic restoring force of the elastic support body, in a seismic isolation unit applied to the structures such as building etc. or the structures such as bridge etc. for reducing and damping the vibration that is transmitted to the construction at the time of earthquake. SOLUTION: Besides the elastic support body 3 is provided integrally in a frame body 2, a plurality of elastic support units 1 providing integrally a mobile support body 4 capable of moving relatively to the longitudinal direction of the frame body 2 and the elastic support body 3 are arranged in piles on the upper part of its elastic support body 3 so that the longitudinal direction of the frame body 2 crosses mutually.
