PROBLEM TO BE SOLVED: To improve running stability at the time of turning of a vehicle.SOLUTION: The present invention includes a pair of right and left trailing arms 2 each having a front end portion supported by a vehicle body and a rear end portion supporting a rear wheel 20, a pair of right and left control arms 5 each located to separate from an axle in the front to back direction, extending in the right to left direction, and having an outer end portion attached via an outer bush 5C to the trailing arm 2 and an inner end portion attached via an inner bush 5D to the vehicle body, and a stabilizer 7 having right and left end portions 7e respectively connected to the control arms 5. At least one of the bushes 5C and 5D is configured to be deformed not horizontally but rather vertically, and the bush is an isotropic bush 10 having characteristics to displace the trailing arm 2 so that the wheel 20 is displaced in a towing direction when the control arm 5 is pushed downward by reaction force of the stabilizer 7 at the time of turning of a vehicle.SELECTED DRAWING: Figure 4

    【課題】車両旋回時の走行安定性を向上させる。【解決手段】前端部が車体に支持されるとともに後端部において車輪20を支持する左右一対のトレーリングアーム2と、車軸に対し前後方向に離隔した位置で左右方向に延設され、外端部が外ブッシュ5Cを介してトレーリングアーム2に取り付けられるとともに内端部が内ブッシュ5Dを介して車体に取り付けられた左右一対のコントロールアーム5と、左右の各端部7eが各々のコントロールアーム5に連結されたスタビライザ7と、を備える。ブッシュ5C,5Dの少なくとも一方は、左右方向よりも上下方向に変位しやすく構成されるとともに、車両旋回時のスタビライザ7の反力によってコントロールアーム5が下方へ押された場合に、車輪20がトーイン方向へ変位するようにトレーリングアーム2を変位させる特性を持った異方性ブッシュ10である。【選択図】図4
