PROBLEM TO BE SOLVED: To provide a vibration-proof bush capable of setting a low spring characteristic even in any direction regarding a bush axis right-angle direction, setting mutually different characteristics regarding mutually orthogonal two directions and further reducing the number of components or man-hours for assembly.SOLUTION: A vibration-proof bush is configured by combining an outer sleeve with a rubber-like elastic body that is held at an inner peripheral side of the outer sleeve. Multiple rib shapes are provided on a circumference of an inner peripheral surface of the rubber-like elastic body, and a mating fitting component is press-fitted and mounted at an inner peripheral side of the multiple rib shapes without adhesion. A bored part is provided in a part on the circumference of the rubber-like elastic body. A length of partial rib shapes on the circumference is set shorter than a length of rib shapes in the other portion.SELECTED DRAWING: Figure 1 【課題】ブッシュ軸直角方向に関して、いずれの方向についても低バネの特性を設定することができ、互いに直交する２方向について互いに異なる特性を設定することができ、しかも部品点数や組立て工数を削減することができる防振ブッシュを提供する。【解決手段】アウタースリーブと、このアウタースリーブの内周側に保持されたゴム状弾性体との組み合わせよりなり、ゴム状弾性体の内周面に円周上複数のリブ形状を設け、複数のリブ形状の内周側に相手取付部品を非接着で圧入装着することを特徴とする。また、ゴム状弾性体の円周上一部に、すぐり部を設けたことを特徴とする。また、円周上一部のリブ形状の長さを他の部分のリブ形状の長さよりも小さく設定したことを特徴とする。【選択図】図１
