Further, the landing provided on the peripheral wall of the hoistway formed in the base building can be used as a landing having a normal structure, which has an effect of facilitating installation. In addition, since the opposite sides of the rail holding frame are connected by the intermediate reinforcing material, the rigidity of the rail holding frame is improved, and the horizontal position of the guide rail row in the horizontal plane is more reliably maintained when the base-isolated building is displaced in the horizontal direction. This has the effect of effectively preventing the elevating body from deviating from the guide rail row.

Further, as described above, the present invention is provided with the longitudinal reinforcing members which are connected to the rail holding frames which are arranged in the vertical direction and are separated from each other in the elastic deformation area. .

This has the effect of preventing the occurrence of inconveniences. Further, the landing provided on the peripheral wall of the hoistway formed in the base building can be used as a landing having a normal structure, which has an effect of facilitating installation. In addition, since the plurality of rail holding frames are connected by the vertical reinforcing members, the rigidity of the rail holding frames in the direction perpendicular to the vertical direction increases, and when the seismic isolation building is displaced in the horizontal direction, the horizontal direction of the guide rail row is changed. Reduces the amount of elastic deformation. Therefore, the behavior due to the horizontal elastic deformation of the guide rail row when the seismic isolation building is displaced in the horizontal direction is stabilized, and the occurrence of trouble when the seismic isolation building is displaced in the horizontal direction is reduced, which is effective.
