DAMPER ATTACHMENT STRUCTURE OF SEISMIC ISOLATOR
To suppress a phenomenon that the deterioration of a damper is early progressed at a peripheral portion of an insertion port of an insertion hole of an attachment base part, in a "damper attachment structure of a seismic isolator".SOLUTION: In a damper attachment structure 10, a damper 1 is fixed to an attachment base part 2 by a plurality of axial fixing tools 23 which penetrate the attachment base part 2 and a center axis of the damper 1. In the damper 1, with respect to an effective cross section area S of a cross section in a diameter direction of a portion which is penetrated with the axial fixing tools 23, an effective cross section area S1 of a cross section in the diameter direction located in a position which is close to an insertion port 212 of a damper insertion hole 211 is equal to or larger than an effective cross section area S2 of a cross section in the diameter direction located in a position which is far from the insertion port 212, and the effective cross section area S1 of a cross section in the direction which is the nearest from the insertion port 212 is larger than an effective cross section area S3 of a cross section in the diameter direction which is the farthest from the insertion port 212.SELECTED DRAWING: Figure 4
【課題】「免震装置におけるダンパー取付け構造」において、取付け用基台部の挿入孔の挿入口の周辺部分において、ダンパーの劣化が早期に進行してしまう現象を抑制する。【解決手段】取付け用基台部２とダンパー１の中心軸とを貫通する複数の軸状の固定具２３によって、ダンパー１は、取付け用基台部２に固定されていて、ダンパー１は、各々の軸状の固定具２３が貫通している部分の直径方向断面における有効断面積Ｓについて、ダンパー挿入孔２１１の挿入口２１２からより近い位置にある直径方向断面の有効断面積Ｓ１が、挿入口２１２からより遠い位置にある直径方向断面の有効断面積Ｓ２と同等以上であって、尚且つ、挿入口２１２から最も近い直径方向断面の有効断面積Ｓ１が、挿入口２１２に最も遠い直径方向断面の有効断面積Ｓ３よりも大きい、ダンパー取付け構造１０とする。【選択図】図４
