To provide a vehicle suspension device which can prevent change in pitching behavior of the entire vehicle when a regenerative brake and a friction brake are used in the vehicle including an electric motor.SOLUTION: The invention relates to a suspension device of a vehicle including electric motors 30, 32 and includes: a front suspension arm 66 that may swing in a vehicle vertical direction with reference to a front wheel swinging axis A; a front damper 68 extending substantially perpendicularly to the front wheel swinging axis A in a side view; a rear suspension arm 46 that may swing in the vehicle vertical direction with reference to a rear wheel swinging axis A; and a rear damper 48 extending substantially perpendicularly to the rear wheel swinging axis A in the side view. In the side view, the front wheel swinging axis A and a first imaginary line C perpendicular to a direction of extension of the front damper are substantially parallel to each other. Further, the rear wheel swinging axis A and a second imaginary line C perpendicular to a direction of extension of the rear damper are substantially parallel to each other.SELECTED DRAWING: Figure 10 【課題】電動機を備えた車両において、回生ブレーキおよび摩擦ブレーキの使用時における車両全体のピッチング挙動の変化を抑制することができる車両のサスペンション装置を提供する。【解決手段】本発明は、電動機３０、３２を備える車両のサスペンション装置であって、前輪揺動軸線Ａを基準に車両上下方向に揺動可能なフロントサスペンションアーム６６と、側面視で前輪揺動軸線Ａに対してほぼ垂直に延びるフロントダンパ６８と、後輪揺動軸線Ａを基準に車両上下方向に揺動可能なリアサスペンションアーム４６と、側面視で後輪揺動軸線Ａに対してほぼ垂直に延びるリアダンパ４８とを備え、側面視において、前輪揺動軸Ａと、フロントダンパが延びる方向に直交する第１仮想線Ｃとがほぼ平行であり、且つ、後輪揺動軸Ａと、リアダンパが延びる方向に直交する第２仮想線Ｃとがほぼ平行である。【選択図】図１０
