To provide a rubber bush capable of suppressing a displacement amount even in a case where an input frequency of a large load is high.SOLUTION: A shaft center metal fitting 2 is provided. On a radially outward side of the shaft center metal fitting 2, a housing 3 is arranged. Between the shaft center metal fitting 2 and the housing 3, a rubber elastic body 4 is interposed. In the rubber elastic body 4, a stopper 6 is provided. The stopper 6 is opposite to the shaft center metal fitting 2 and the housing 3 at intervals 7, 8, respectively. When a large load is input to a rubber bush 1, the stopper 6 contacts with both of the shaft center metal fitting 2 and the housing 3. A displacement amount of the rubber elastic body 4 is restricted to suppress fatigue of the rubber elastic body 4.SELECTED DRAWING: Figure 3

    【課題】大きな荷重の入力頻度が高い場合にも、変位量を抑えることのできるゴムブッシュの提供。【解決手段】軸心金具2を設ける。軸心金具2の径方向外側にハウジング3を配置する。軸心金具2とハウジング3との間にゴム状弾性体4を介在させる。ゴム状弾性体4にストッパー6を設ける。ストッパー6を軸心金具2及びハウジング3のそれぞれと隙間7、8をあけて対向させる。ゴムブッシュ1に大きな荷重を入力した際、ストッパー6を軸心金具2及びハウジング3の両方に当接させる。ゴム状弾性体4の変形量を制限してゴム状弾性体4の疲労を抑える。【選択図】 図3
