To provide a vibration-proof support structure which not only surely exhibits original vibration-proof effect by an elastic support structure but also prevents generation of fretting wear and noise.SOLUTION: In a vibration-proof support structure 3, a first hole 20 is so large that a first fastening body 11 does not contact with a socket 17 and a projection 11a for alignment of a first vibration-proof rubber 13 and a recess 11b for alignment of a second vibration-proof rubber 14 are formed in a neighborhood of the first hole 20 of the first fastening body 11. Second alignment holes 21 are formed penetrating the first fastening body 11 and a first plate 15.SELECTED DRAWING: Figure 8

    【課題】弾性支持による本来の防振効果を確実に発揮するとともに、フレッティング摩耗及び騒音の発生を防止する。【解決手段】防振支持構造体3において、第1の穴20は、第1の締結体11がソケット17に接触しない程度に大きく、第1の締結体11における第1の穴20の近傍に、第1の防振ゴム13の位置合わせ用の凸部11a及び第2の防振ゴム14の位置合わせ用の凹部11bが形成される。また、第1の締結体11及び第1のプレート15を貫いて、位置合わせ用の第2の穴21が形成される。【選択図】図8
