PROBLEM TO BE SOLVED: To provide a vibration-proof device having a new structure capable of assuring a large abutting area at the first stopper and reducing a shearing force acted on a connecting bolt by a stopper load.SOLUTION: This invention relates to a vibration-proof device 10 having the first stopper for restricting a relative displacement amount of a first fixing member 12 and a second fixing member 14. A first bracket 76 is formed with a first abutting protrusion 94 protruded toward an overlapped side for the first fixing member 12, a first opposing surface 126 of the first fixing member 12 facing against a second bracket 78 is covered by the first abutting protrusion 94. The first stopper is constituted by abutment between the first bracket 76 and the second bracket 78 in a direction of the first stopper and at the same time an abutting surface of the first bracket 76 at the first stopper is constituted to include the first abutting protrusion 94.SELECTED DRAWING: Figure 8

    【課題】第一のストッパにおける当接面積を大きく確保できると共に、ストッパ荷重によって連結ボルトに作用する剪断力を低減することができる、新規な構造の防振装置を提供すること。【解決手段】第一の取付部材12と第二の取付部材14の相対変位量を第一のストッパ方向で制限する第一のストッパを備えた防振装置10において、第一のブラケット76には第一の取付部材12への重ね合わせ側に向かって突出する第一の当接突部94が形成されていると共に、第二のブラケット78に対して対向する第一の取付部材12の第一の対向面126が第一の当接突部94によって覆われている。そして、第一のストッパが第一のブラケット76と第二のブラケット78の第一のストッパ方向での当接によって構成されるようになっていると共に、第一のストッパにおける第一のブラケット76側の当接面が、第一の当接突部94を含んで構成されるようにした。【選択図】図8
