Zusammenfassung:To provide a vehicle suspension device which can prevent change in behavior of a 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 10 of a vehicle 1 including an electric motor 30, which transmits drive force to wheels 34 through output transmission shafts 32. The suspension device includes: a suspension arm 46 which is coupled to a vehicle body side and a wheel side and may swing in a vehicle vertical direction; and a damper 48 which extends substantially perpendicular to a swinging axis A in a vehicle body side mounting portion of the suspension arm 46 in a side view. In the side view, the swinging axis A of the suspension arm 46 and an imaginary line C perpendicular to a direction of extension of the damper 48 are substantially parallel to each other.SELECTED DRAWING: Figure 6 【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の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、出力伝達軸32を介して車輪34に駆動力を伝達する電動機30を備える車両1のサスペンション装置10であって、車体側および車輪側に連結され、車両上下方向に揺動可能なサスペンションアーム46と、側面視において、サスペンションアーム46の車体側取付け部における揺動軸線Aに対してほぼ垂直に延びるダンパ48と、を備え、側面視において、サスペンションアーム46の揺動軸線Aと、ダンパ48が延びる方向に直交する仮想線Cとがほぼ平行である。【選択図】図6
