PROBLEM TO BE SOLVED: To provide an in-wheel motor driving device which enables a connection portion between an in-wheel motor and a vehicle body side member to be located closer to an axis of a wheel than conventional in-wheel motor driving devices.SOLUTION: A casing (43) of an in-wheel motor driving device (10) includes: a cylindrical body first casing (43g) disposed at one side in an axis (O) direction; and a cylindrical body second casing (43a) disposed at the other side in the axis direction. The body first casing and the body second casing respectively have annular butted parts (43j) butted with each other in the axis direction. A hub carrier (18) has a connection part (82s) for rotatably connecting to a vehicle body side member (81) at a tip. An axial position of the connection part is arranged so as not to overlap with an axial position of the butted surface and so as to overlap with an axial position of the body first casing or the body second casing.SELECTED DRAWING: Figure 3
【課題】インホイールモータと車体側メンバの連結箇所を従来よりも車輪の軸線に近づけることができるインホイールモータ駆動装置を提供する。【解決手段】インホイールモータ駆動装置(10)のケーシング(43)は、軸線(O)方向一方側に配置される筒状の本体第1ケーシング(43g)と、軸線方向他方側に配置される筒状の本体第2ケーシング(43a)とを含み、本体第1ケーシングおよび本体第2ケーシングは軸線方向に互いに突き合わされる環状の突合面(43j)をそれぞれ有し、ハブキャリア(18)は先端に車体側メンバ(81)と回動可能に連結するための連結部(82s)を有する。連結部の軸線方向位置が、突合面の軸線方向位置と重ならず、本体第1ケーシングあるいは本体第2ケーシングの軸線方向位置と重なるよう配置される。【選択図】図3
