To provide a sliding seismic isolation mechanism which has a small installation area and restoring force having a large load capacity.SOLUTION: In a sliding seismic isolation mechanism, a sliding element 5 disposed between an upper guide member 2 and a lower guide member 4 comprises: an upper tier sliding element 6; a lower tier sliding element 8; and a middle tier sliding element 7 disposed between the upper tier sliding element 6 and the lower tier sliding element 8. The sliding seismic isolation mechanism is disposed so that the lower tier sliding element 8 and the middle tier sliding element 7 are engaged in a manner that the lower tier sliding element 8 and the middle tier sliding element 7 can rotate around a y axis extending in a y direction and cannot rotate around an x axis extending in an x direction and the upper tier sliding element 6 and the middle tier sliding element 7 are engaged in a manner that the upper tier sliding element 6 and the middle tier sliding element 7 can rotate around the x axis and cannot rotate around the y axis.SELECTED DRAWING: Figure 2
【課題】設置面積が小さく耐荷重の大きい復元力をもつ滑り免震機構を提供する。【解決手段】上部案内部材２と下部案内部材４の間に介装される摺動子５を、上段摺動子６と、下段摺動子８と、上段摺動子６と下段摺動子８の間に介装される中段摺動子７とで構成する。また、下段摺動子８と中段摺動子７がｙ方向に延びるｙ軸周りに回転可能、且つｘ方向に延びるｘ軸周りに回転不能に係合し、上段摺動子６と中段摺動子７がｘ軸周りに回転可能、且つｙ軸周りに回転不能に係合するように構成する。【選択図】図２
