PROBLEM TO BE SOLVED: To prevent bending deformation from occurring in rubber included in a vertical rigidity adjustment mechanism of a slide bearing base isolation device, and to set vertical rigidity of the rubber without considering influence of bending deformation.SOLUTION: A vertical rigidity adjustment mechanism 50 includes: a laminated rubber 51 that is provided so as to be overlapped with an elastic slide bearing 40 in a vertical direction in an elastic slide bearing base isolation device 30, and on which a load of a superstructure 12 to be a base isolation object on the elastic slide bearing base isolation device 30 acts; and a horizontal constraint part 52 that is provided so as to surround the periphery of the laminated rubber 51. Here, the horizontal constraint part 52, while allowing deformation of the laminated rubber 51 in the vertical direction, constrains deformation of the laminated rubber 51 in a horizontal direction continuously from the upper end of the laminated rubber 51 to the lower end thereof.SELECTED DRAWING: Figure 3
