- 弾性層及び剛性層が積層方向において交互に積層されていると共に積層方向に伸びた中空部を有している積層弾性体と、塑性変形により振動エネルギを吸収するように積層弾性体の中空部に配された塑性体と、積層方向における一端部及び他端部が塑性体に囲繞されるように当該塑性体内に埋設されている積層方向に伸びた剛性部材とを具備しており、剛性部材は、積層方向に伸びていると共に中空部に配された塑性体よりも短い棒状本体と、この棒状本体の積層方向における一端部に設けられていると共に塑性体の積層方向における一端部に向かって凸となっている半球面状の凸曲面と、棒状本体の積層方向における他端部に設けられていると共に塑性体の積層方向における他端部に向かって凸となっている半球面状の凸曲面とを具備しており、剛性部材の鉛直方向における長さは、鉛直荷重載荷時に生じる初期弾性量及び将来生じると想定できるクリープ量を差し引いた積層弾性体の鉛直方向における長さよりも短くなっている免震支承。
- 塑性体が中空部に封入されるように当該塑性体の積層方向における一端部及び他端部を閉塞する閉塞部を具備している請求項1に記載の免震支承。
- 塑性体は、鉛、錫、錫合金又は熱可塑性樹脂製であり、剛性部材は、鉄、銅、銅合金、アルミ又はアルミ合金製である請求項1又は2に記載の免震支承。
