To properly arrange a suspension device and an in-wheel motor so that an outside diameter of a motor part is not sacrificed, and to improve the rigidity and stiffness of a connecting part.SOLUTION: An in-wheel motor drive unit 10 comprises: a hub ring 12 connectedly fixed to a wheel; a wheel hub bearing part 11 having a fixed ring arranged at the hub ring coaxially therewith, and a plurality of rolling bodies arranged in an annular space which is formed of the hub ring and the fixed ring; a motor part 21 arranged eccentrically from an axial line O of the wheel hub bearing part, and driving the hub ring; and a knuckle 41 connected to a damper 52 of the suspension device 51. The knuckle has an upper-side connecting portion 47 connected to a vertical-direction center region of the damper at an upper part rather than an axial line, and a lower-side connecting portion 48 connected to a lower end part of the damper at a lower part rather than the axial line.SELECTED DRAWING: Figure 1

    【課題】モータ部の外径が犠牲にならないようサスペンション装置とインホイールモータの連結部を適正に配置するとともに、連結部の強度および剛性を向上させる。【解決手段】インホイールモータ駆動装置10は、車輪に連結固定されるハブ輪12、ハブ輪と同軸に配置される固定輪、およびハブ輪と固定輪の環状空間に配置される複数の転動体を有する車輪ハブ軸受部11と、車輪ハブ軸受部の軸線Oから偏心して配置されてハブ輪を駆動するモータ部21と、サスペンション装置51のダンパ52に連結されるナックル41とを備える。ナックルは、軸線よりも上方でダンパの上下方向中央領域に連結される上側連結部分47と、軸線よりも下方でダンパの下端部に連結される下側連結部分48とを有する。【選択図】図1
