An object of the present invention is to provide an in-wheel motor driving device which has a deceased axial dimension and includes aluminum alloy housings having a minimum wall thickness for reduced weight while retaining good assemblability. An in-wheel motor driving device includes a wheel braking device. A back plate 71b of a drum brake 71 or a mounting member 72c for calipers 72b of a disc brake 72 constituting the wheel braking device is formed integrally with an outboard-side end member 22d which is fastened to a outboard-side end surface of a housing 22b of a speed reducer section B, for reduced number of parts and minimal axial dimension. |
