To solve the problem of being unable to avoid interference of the other vehicle body structure and a member due to being no degree of freedom of a shape in a connection member, however, by showing to be capable of reducing a camber angle change of a tire to a vertical movement of a vehicle body and the ground surface of a turning roll time by forming a vehicle body central part of its connection member in a lower shape than the vehicle body outside, by connecting a pair of left-right upper links by the connection member low in torsional rigidity and high in flexural rigidity of an independent suspension type suspension in the previous application.SOLUTION: A connection member low in torsional rigidity and high in flexural rigidity is arranged on the left-right of a vehicle body, and a degree of freedom is imparted to a shape in a rigid body part of a vehicle body central part by connecting the central part by a rigid body. Thus, interference with the other vehicle body structure and a member can be avoided, and a range of an applicable vehicle can be expanded.SELECTED DRAWING: Figure 17
【課題】先願において、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とができることを示した。しかし上記連結部材には形状の自由度が無く他の車体構造ならびに部材との干渉を避けることが出来なかった。【解決手段】本発明は、捩じり剛性が低く曲げ剛性の高い連結部材を車体左右に配置し、中央部を剛体で連結することにより車体中央部の剛体部分での形状に自由度を持たせた。これにより他の車体構造ならびに部材との干渉を避けることが出来りようになり適用できる車両の範囲を広げることができるようになった。【選択図】図17
