Kind Code:
B2
Abstract:
To provide a seismic isolation device capable of achieving preferable seismic isolation performance even under a low temperature condition and increasing merchantability. A seismic isolation device 1 includes upper and lower spherical panels 10, 10 and a sliding body 20. The sliding body 20 includes a base portion 21 and upper and lower sliding members 22, 22 formed on the respective upper and lower end portions of the base portion 21. On the sliding surface 22a of each sliding member 22, multiple holes h0 to h6 are formed, and the multiple holes h0 to h6 are filled with solid lubricant material 23. The holes h1 to h6 are non-linearly disposed in a direction along a straight line H, so that the width (S3 to S2) between a maximum value and a minimum value on a curved line indicating a change in the sum SumL of the distances traversing the holes h1 to h6 in respective directions with the center hole h0 as a reference is small, as compared with a case in which the holes h1 to h6 are linearly disposed in the direction along the straight line H.
