    • A seismic isolation device comprises a floor body which is arranged on a structural floor and to which an object of seismic isolation is mounted, a first restoring member disposed on the structural floor and adapted to impart a horizontal restoring force to the floor body when the floor body is horizontally displaced with respect to the structural floor, a first damping member arranged in association with the first restoring member and adapted to impart a horizontal damping force when the floor body is horizontally displaced with respect to the structural floor, a first engaging member projecting from the floor body towards the structural floor, a second engaging member provided on the first restoring member and sliding while coming into contact with the first engaging member, a second restoring member disposed to a lower portion of the floor body and adapted to impart a vertical restoring force when the floor body is vertically displaced with respect to the structural floor, a second damping member arranged in association with the second restoring member and adapted to impart a vertical damping force when the floor body is vertically displaced with respect to the structural floor, and a support mechanism for supporting the floor body to be movable in a horizontal direction.
    • 隔震装置包括布置在结构地板上并且安装有隔震物体的地板本体,设置在结构地板上的第一恢复构件,并且适于在地面上施加水平恢复力到地板本体 主体相对于结构地板水平移位,第一阻尼构件与第一恢复构件相关联地布置并且适于当地板本体相对于结构地板水平移位时施加水平阻尼力;第一接合构件突出 从所述地板本体向结构地板施加第二接合构件,所述第二接合构件设置在所述第一恢复构件上并在与所述第一接合构件接触的同时滑动;第二恢复构件,设置在所述地板本体的下部, 当地板体相对于结构地板垂直移位时的恢复力,第二 阻尼构件,其与所述第二恢复构件相关联地布置并且适于在所述地板主体相对于所述结构地板垂直移位时施加垂直阻尼力;以及支撑机构,用于支撑所述地板本体以在水平方向上可移动。
