PROBLEM TO BE SOLVED: To provide a seismic base isolator damper for a structure in which the seismic base isolator damper has a simple structure, its manufacturing can be carried out by an exclusive die, vulcanization adhering for elastic rubber, a lead or tin cylindrical member, its press fitting are facilitated and requisite seismic energy absorbing performance is included.SOLUTION: This invention comprises a cylindrical member fixed to one structure that is relatively displaced at the time of occurrence of an earthquake and a rod member fixed to the other structure, extending from an opening of the cylindrical member into the inside of it and arranged to enable relative displacement to be carried out between it and the cylindrical member. The cylindrical member is constituted by a plurality of unit cylindrical bodies, at least one outer peripheral part in a ring-like elastic plastic rubber formed with hole for inserting and passing the rod member in the inner wall for every unit cylindrical body, lead or tin, elastic plastic rubber and lead or tin seismic energy absorbing member is fixed, the plurality of unit cylindrical bodies are integrally connected to form a cylindrical member, and a relative displacement between the cylindrical member and the rod member at the time of occurrence of an earthquake is acted on the seismic energy absorbing member to absorb the seismic energy..SELECTED DRAWING: Figure 1 |
