Zusammenfassung:	PROBLEM TO BE SOLVED: To provide fixing equipment of a seismic isolation device which does not require replacement of an aseismic shear pin with a wind resistant shear pin before being hit by a typhoon.SOLUTION: A seismic isolation device 20 comprises: seismic isolation means 21 installed between a substructure 3 and a superstructure 6; and a shear pin 23 which releases restriction of the seismic isolation means 21 on the occurrence of an earthquake. A pair of bolt supporting bodies 42 with push bolts 41 screwed thereinto is installed on either one of the substructure 3 or the superstructure 6. Bolt receiving sections 43 positioned opposite to tips of the push bolts are installed on the other of the substructure or the superstructure 6. 【課題】台風襲来前に、地震用のせん断ピンを台風用のせん断ピンと交換する必要がない免震装置における固定装置を提供する。【解決手段】下部構造物３と上部構造物６の間に、免震手段２１と、地震発生時に前記免震手段の束縛を解除するせん断ピン２３とを設置した免震装置２０において、前記下部構造物３と前記上部構造物６の何れか一方に押しボルト４１を螺着した一対のボルト支持体４２を設置し、他の一方の構造物に前記押しボルトの先端に対峙するボルト受け部４３を設置する。【選択図】図１
