PROBLEM TO BE SOLVED: To provide a coupling structure of an in-wheel motor drive device capable of decreasing a distance from a wheel center of a wheel to a steering shaft, and a suspension device.SOLUTION: An in-wheel motor drive device (10) is equipped with a wheel hub bearing portion (11); a motor portion (21) and a speed reducing portion (31) offset-arranged on an upper side to an axis of the wheel hub bearing portion; and a carrier (101) projecting out to a lower side than the wheel hub bearing portion. At a lower end of the carrier, a suspension coupling portion (101c) for being coupled to a suspension device (116) in any direction at a lower end of the carrier, is provided. Concerning an axial direction position of the wheel hub bearing portion, the suspension coupling portion is disposed so as to be superimposed on the wheel hub bearing portion.SELECTED DRAWING: Figure 4

    【課題】車輪のホイールセンタから転舵軸までの距離を小さくすることができるインホイールモータ駆動装置とサスペンション装置の連結構造を提供する。【解決手段】インホイールモータ駆動装置(10)は、車輪ハブ軸受部(11)と、車輪ハブ軸受部の軸線に対して上側にオフセット配置されるモータ部(21)および減速部(31)と、車輪ハブ軸受部よりも下側へ突出するキャリア(101)を備える。キャリアの下端にはサスペンション装置(116)と方向自在に連結するためのサスペンション連結部(101c)が設けられる。車輪ハブ軸受部の軸線方向位置に関し、サスペンション連結部は車輪ハブ軸受部と重なるように配置される。【選択図】図4
