To provide an in-wheel motor drive device in which vibration caused by deformation of a stator is hardly transmitted to a vehicle body, and a rotary motor used for the same.SOLUTION: An in-wheel motor drive device IWM comprises a rotary motor 1, a wheel bearing 5, and a speed reducer 2. The rotary motor 1 has an annular stator 9, a housing 8 in which the stator 9 is fitted and fixed therein, a rotary shaft 6 that is rotatably supported on the housing 8 through bearings 11,12 coaxially with the stator 9, and a rotor 10 rotating integrally with the rotary shaft 6. A non-contact section A is provided between an outer peripheral surface of the stator 9 and an inner peripheral surface of the housing 8. A vehicle body mounting piece 51 protrudes from an outer peripheral surface of the housing 8. A part or all of a base end of the vehicle body mounting piece 51 overlaps with a radial projection area of the non-contact section A.SELECTED DRAWING: Figure 1

    【課題】ステータの変形に起因する振動が車体に伝わり難いインホイールモータ駆動装置およびそれに用いられる回転電動機を提供する。【解決手段】インホイールモータ駆動装置IWMは、回転電動機1と、車輪用軸受5と、減速機2とを備える。回転電動機1は、環状のステータ9と、ステータ9が内部に嵌合しかつ固定されたハウジング8と、ハウジング8に軸受11,12を介してステータ9と同軸心に回転自在に支持された回転軸6と、回転軸6と一体に回転するロータ10とを有する。ステータ9の外周面とハウジング8の内周面との間に非接触部Aが設けられている。ハウジング8の外周面から車体取付片51が突出している。車体取付片51の基端の一部または全部が非接触部Aの径方向投影領域に重なる。【選択図】図1
