PROBLEM TO BE SOLVED: To achieve high stability during turning of a vehicle while improving flexibility of the layout of members.SOLUTION: A rear suspension device 1 includes: a cross member 8 which is disposed under a vehicle body and supports a pair of left and right arms 4 on both sides in the vehicle width direction; a stabilizer 7 which is extended in the vehicle width direction, connects between a pair of left and right arms 4 and whose middle part is mounted on the cross member 8. The cross member 8 is elastically supported on the vehicle body through vehicle body bushes 10, 20 in each of a pair of a front side mount part 8f and a rear side mount part 8r on both of left and right sides. Each of the two vehicle body bushes 10, 20 mounted on at least either one of the front side mount part 8f and the rear side mount part 8r is an inclination characteristic bush which can be displaced in such a direction as to incline horizontally to the perpendicular direction, is provided to be symmetrical with regard to the horizontal direction and has a function of displacing the cross member 8 to be turned inward by a reaction of the stabilizer 7 during vehicle turning.SELECTED DRAWING: Figure 5

    【課題】部材の配置自由度を高めつつ車両旋回時の走行安定性を向上させる。【解決手段】リヤサスペンション装置1は、車体の下方に配置されて車幅方向における両側部に左右一対のアーム4を支持するクロスメンバ8と、車幅方向に延設され、左右一対のアーム4間を連結するとともに中間部がクロスメンバ8に取り付けられるスタビライザ7と、を備える。クロスメンバ8は、左右両側に一対で設けられた前側マウント部8f及び後側マウント部8rのそれぞれにおいて車体ブッシュ10,20を介して車体に弾性支持される。前側マウント部8f及び後側マウント部8rの少なくともいずれか一方に設けられる二つの車体ブッシュ10,20は、鉛直方向に対して左右に傾斜した方向に変位可能とされるとともに左右対称に設けられ、車両旋回時のスタビライザ7の反力によってクロスメンバ8を旋回内向きに変位させる機能を有する傾斜特性ブッシュである。【選択図】図5
