ダンパ。[Scope of Claim for Utility Model Registration] (1) A seismic isolation device installed at the foundation of a structure, which is a seismic isolation device that is provided by the plastic deformation of an elastoplastic body that is pivotally supported together with a support that supports the structure. In a steel bar damper for a seismic isolation device that attenuates earthquake energy, the steel bar damper is made by alternately stacking cylindrical elastic bodies and steel rings, and the heights of the elastic bodies and steel rings are sequentially changed. Therefore, the laminated body is tapered to form a laminated body, the laminated body is attached to a main body to form a laminated bushing, the elastic plastic body is connected and fixed to the laminated bushing, and in the event of an earthquake, the laminated body is attached to the laminated bushing. A steel rod damper characterized by being formed so that it can be pulled out from the main body. (2) The steel rod damper according to claim 1, wherein the elastic body of the laminate is made of high damping rubber.
