To assure steering stability when turning.SOLUTION: A pressure receiving area of any one liquid chamber, to which a compressive force is added, of a front side liquid chamber 16a and a rear side liquid chamber 16b in antivibration bushes 21, 22 which are positioned on a turning outside is larger than a pressure receiving area of any one liquid chamber, which is communicated with said one liquid chamber in the antivibration bushes which are positioned on the turning outside through a first pipeline 17 or a second pipeline 18 and to which a compressive force is added, of a front side liquid chamber and a rear side liquid chamber in antivibration bushes which are positioned on a turning inside. A pressure receiving area of the other liquid chamber, to which a tensile force is added, of the front side liquid chamber and the rear side liquid chamber in the antivibration bushes which are positioned on the turning outside is larger than a pressure receiving area of the other liquid chamber, which is communicated with the other liquid chamber in the antivibration bushes which are positioned on the turning outside through the first pipeline or the second pipeline and to which a tensile force is added, of the front side liquid chamber and the rear side liquid chamber in the antivibration bushes which are positioned on the turning inside.SELECTED DRAWING: Figure 1
【課題】旋回時の操縦安定性を確保する。【解決手段】旋回外側に位置する防振ブッシュ21、22における前側液室16aおよび後側液室16bのうち、圧縮力が加えられるいずれか一方の液室の受圧面積が、旋回内側に位置する防振ブッシュにおける前側液室および後側液室のうち、第1配管17または第2配管18を通して、旋回外側に位置する防振ブッシュにおける前記一方の液室に連通し、かつ圧縮力が加えられるいずれか一方の液室の受圧面積より大きく、旋回外側に位置する防振ブッシュにおける前側液室および後側液室のうち、引張力が加えられるいずれか他方の液室の受圧面積が、旋回内側に位置する防振ブッシュにおける前側液室および後側液室のうち、第1配管または第2配管を通して、旋回外側に位置する防振ブッシュにおける前記他方の液室に連通し、かつ引張力が加えられるいずれか他方の液室の受圧面積より小さい。【選択図】図1
