To provide a structure which prevents damage of an in-wheel motor drive device at the front collision of an electric vehicle.SOLUTION: A suspension structure for an in-wheel motor drive device comprises: a lower arm which is coupled to a vehicle body side member; and a ball joint 49 which couples the in-wheel motor drive device to the lower arm in a free direction. By comparing the front side maximum angle βf at which the angle change of a stud part 49t of the ball joint 49 is allowed in the vehicle cross direction with respect to a socket 49s with a ball 49b of the ball joint 49 as a center with the maximum angle in the vehicle width direction, the front side maximum angle βf is narrower than the maximum angle in the vehicle width direction.SELECTED DRAWING: Figure 7

    【課題】電動車両の前方衝突時にインホイールモータ駆動装置の破損を防止する構造を提供する。【解決手段】インホイールモータ駆動装置用サスペンション構造は、車体側メンバに連結されるロアアームと、インホイールモータ駆動装置をロアアームに方向自在に連結するボールジョイント49を備える。ボールジョイント49のボール49bを中心としてボールジョイント49のスタッド部49tがソケット49sに対して車両前後方向に角度変更を許容される前側最大角度βfと、車幅方向の最大角度を対比して、車幅方向の最大角度よりも前側最大角度βfの方が狭い。【選択図】図7
