To solve the problems in an independent suspension type suspension that, although excellent ride comfort is obtained since left and right tires are mutually independently movable, a camber angle change is caused in a tire relative to the ground surface during vertical motion and turning roll of a vehicle, and that ride comfort, straightness and turning stability are obstructed by the camber angle change.SOLUTION: In a vehicular suspension, a left and right pair of upper links of an independent suspension type suspension are twisted and connected by a connection member having low rigidity and high bending rigidity. Further, the vehicular suspension is shaped such that a vehicle central part of the connection member is lower than a vehicle exterior side, in order to reduce a camber angle change of a tire relative to the ground surface during vertical motion and turning roll of the vehicle. Accordingly, ride comfort and straightness are improved, and decrease in cornering force required for turning is suppressed, so that improvement in stability during turning is achieved.SELECTED DRAWING: Figure 1

    【課題】独立懸架式のサスペンションにおいて左右タイヤは相互に独立に動くことができるため良好な乗り心地を得ることはできるが、車体の上下動および旋回ロール時に地面に対してタイヤにキャンバー角変化が生じてしまう。このキャンバー角変化により乗り心地、直進性および旋回安定性が阻害されていた。【解決手段】本発明は、独立懸架式サスペンションの左右一対のアッパーリンクを捩じり剛性が低く曲げ剛性の高い連結部材で連結し、その連結部材の車体中心部分を車体外側より低い形状とすることにより車体の上下動および旋回ロール時の地面に対するタイヤのキャンバー角変化を低減する。これにより乗り心地と直進性の向上および旋回に必要なコーナリングフォースの低下を抑止し旋回時の安定性向上が計られる。【選択図】図1
