To provide a base isolation device more excellent in workability than a conventional one when fixing an upper structure and a lower structure.SOLUTION: A base isolation device 21 includes: a laminated rubber 35 connecting a lower connection plate 33 and an upper connection plate 31 so as to be movable in a horizontal direction; a compression support structure 51 connecting the lower connection plate 33 and the upper connection plate 31 and restraining the lower connection plate 33 and the upper connection plate 31 from moving in a direction of coming close to each other at the connected portion; and a tension support structure 61 connecting the lower connection plate 33 and the upper connection plate 31 and restraining the lower connection plate and the upper connection plate from moving in a direction parallel to the direction where the compression support structure 51 restrains them from moving and being apart from each other at the connected portion.SELECTED DRAWING: Figure 5

    【課題】従来よりも上部構造物と下部構造物を固定する際の作業性に優れた免震装置の提供。【解決手段】下部連結板33と上部連結板31を水平方向に移動可能に連結する積層ゴム35と、下部連結板33と上部連結板31を連結し、連結した部分において下部連結板33と上部連結板31が互いに近づく向きに移動するのを拘束する圧縮支持構造51を備えた免震装置21において、下部連結板33と上部連結板31を連結し、連結した部分において圧縮支持構造51が移動を拘束する向きと平行で互いに離れる向きに移動するのを拘束する引張支持構造61を備えたことを特徴とする免震装置21。【選択図】図5
