To provide a suspension device of an automobile capable of suppressing displacement of an imaginary king pin axis by bringing the imaginary king pin axis and connection portions with a wheel support of respective arms on the upper side of a vehicle close to each other.SOLUTION: A suspension device of an automobile includes an imaginary king pin axis IK which vertically connects an intersection point P1 on imaginary extension lines of an upper arm 4 and a leading arm 5 and an intersection point P2 on imaginary extension lines of a trailing arm 6 and a lower arm 7. The upper arm 4 and the leading arm 5 are connected to a wheel support 10 via pivot portions 46 and 54. Vertically above the intersection P2 on the respective imaginary extension lines of the trailing arm 6 and the lower arm 7 in a side view, the pivot portion 46 of the upper arm 4 and the pivot portion 54 of the leading arm 5 are arranged so as to overlap each other in a longitudinal direction of a vehicle in a plan view, as well as, overlap each other in a vehicle vertical direction and a vehicle width direction in a front view.SELECTED DRAWING: Figure 5

    【課題】仮想キングピン軸と車両上方側の各アームのホイールサポートとの連結部とを近接させて、仮想キングピン軸の変位を抑制することができる自動車のサスペンション装置を提供する。【解決手段】本発明は、アッパアーム4およびリーディングアーム5のそれぞれの仮想延長線上の交点P1と、トレーリングアーム6およびロアアーム7のそれぞれの仮想延長線上の交点P2とを上下に結ぶ仮想キングピン軸IKを有し、アッパアーム4およびリーディングアーム5はホイールサポート10にピボット部46、54を介して連結され、側面視におけるトレーリングアーム6およびロアアーム7のそれぞれの仮想延長線上の交点P2の鉛直方向上方において、アッパアーム4のピボット部46とリーディングアーム5のピボット部54とが、平面視で車両前後方向に重複すると共に正面視で車両上下方向および車幅方向に重複するよう配置されている。【選択図】図5
