To provide a vibration isolation support structure which has higher durability and assembly performance than a conventional structure and can significantly reduce a manufacturing cost.SOLUTION: A vibration isolation support structure comprises, when an axle modulator 2 (object to be supported) is subjected to vibration isolation support from the frame 3 side in a cantilever form, a first bracket 4 which is fixed to one of side faces of the axle modulator 2 and has a channel-shaped side cross section open in a direction away from the side face; and a second bracket 5 which is fixed to a frame 3 side and has a channel shape arranged face-to-face with the first bracket 4, wherein, these are arranged face to face at different heights. Upper flanges 4a and 5a, lower flanges 4b and 5b are overlapped in a vertical direction respectively, the upper flange 4a of the first bracket 4 and the lower flange 4b are nipped with a pair of vibration isolation rubbers 6 and 7 in the vertical direction, the upper flanges 4a and 5a, the lower flanges 4b and 5b are penetrated and fastened respectively with a bolt 8 and a nut 9 (fastening tools) for each vibration isolation rubber 6 and vibration isolation rubber 7 in the vertical direction.SELECTED DRAWING: Figure 1
【課題】従来よりも耐久性及び組付性が良好で且つ製作コストを大幅に低減し得る防振支持構造を提供する。【解決手段】アクスルモジュレータ2(支持物)をフレーム3側から片持ちで防振支持するに際し、アクスルモジュレータ2の片方の側面に固定されて該側面から離間する方向へ開くチャンネル形の側断面を持つ第一ブラケット4と、フレーム3側に固定されて第一ブラケット4と向かい合わせのチャンネル形を成す第二ブラケット5とを備え、これらを段違いに対向させて相互の上部フランジ4a,5a同士及び下部フランジ4b,5b同士を鉛直方向に重ね、第一ブラケット4の上部フランジ4a及び下部フランジ4bを一対の防振ゴム6,7により上下から挟持せしめて該各防振ゴム6,7ごと上部フランジ4a,5a同士及び下部フランジ4b,5b同士をボルト8及びナット9(締結具)により鉛直方向に貫通締結する。【選択図】図1
