Provided is a high-performance sliding seismic isolation device equipped with a sliding body that achieves a surface pressure of 60 MPa. This sliding seismic isolation device (10) is configured from an upper shoe (1) and a lower shoe (2) respectively equipped with a curved sliding surface (1a, 2a), and a columnar steel sliding body (7) between the upper shoe (1) and the lower shoe (2) and equipped with a curved upper surface (4a) and a curved lower surface (4b) which are in contact with the respective shoes. The upper surface (4a) and the lower surface (4b) of the sliding body (7) are equipped respectively with a double-woven fabric layer (5, 6) comprising a PTFE fiber and a fiber having a higher tensile strength than the PTFE fiber, with the PTFE fiber arranged on the sliding surface (1a, 2a) side of the upper shoe (1) and the lower shoe (2). |
