Zusammenfassung:	To provide a seismic isolation structure with a reduced area occupied by an attenuation device and a stopper member compared to when the attenuation device and the stopper member are arranged at different positions.SOLUTION: A seismic isolation structure comprises: a lower structure body; an upper structure body supported by the lower structure body via a seismic isolation device; a stopper member provided at one of the upper structure body and the lower structure body and projecting downwardly or upwardly; a load receiving part provided at the other of the upper structure body and the lower structure body and facing the stopper member; and an attenuation device having one end fitted to the stopper member and the other end fitted to the other of the upper structure body and the lower structure body, and attenuating a vibration by a telescopic movement.SELECTED DRAWING: Figure 1 【課題】減衰装置とストッパー部材とが異なる位置に配置されている場合と比して、減衰装置とストッパー部材とが占める領域を小さすることができる免震構造を得る。【解決手段】免震構造は、下部構造体と、免震装置を介して下部構造体に支持された上部構造体と、上部構造体及び下部構造体の一方に設けられ、下方又は上方へ突設されたストッパー部材と、上部構造体及び下部構造体の他方に設けられ、ストッパー部材と対向する荷重受け部と、ストッパー部材に一端が取り付けられ、他端が上部構造体及び下部構造体の他方に設けられた支持部に取り付けられ、伸縮することで振動を減衰する減衰装置とを有する。【選択図】図１
