Slider for sliding seismic isolation device and sliding seismic isolation device

摘要

An object of the present invention is to provide a predetermined surface pressure to suppress an increase in a friction coefficient, obtain a seismic isolation effect by a sliding seismic isolation device, and suppress bending stress generated in a slider as much as possible, thereby prematurely wearing a sliding material. To provide a slider for a sliding seismic isolation device and a sliding seismic isolation device capable of suppressing variations in friction coefficient. A slider for a steel sliding seismic isolation device, which is disposed between an upper rod 20A and a lower rod 20B having a sliding surface having a curvature, and includes an upper surface 1a and a lower surface 1b having a curvature. 10. The upper surface 1a and the lower surface 1b are provided with recesses 2a and 2b. The recesses 2a and 2b are in the form of counterbore holes and in the form of through holes 2e.
