VIBRATION-PROOF SUPPORT STRUCTURE FOR RAILWAY VEHICLE

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
