An in-wheel motor drive device (1) is disposed inside a wheel (W) of a driving wheel (92). The in-wheel motor drive device (1) is provided with: a motor unit (21) including a motor rotating shaft for rotating the driving wheel, and a motor casing (29) accommodating the motor rotating shaft; and a plurality of cooling fins (41) which are provided in such a way as to project from a vehicle width direction inside end surface (29e) of the motor casing, and which extend in the front-rear direction of the vehicle. In a state in which the orientation of the front-rear direction of the driving wheel (92) is aligned with the orientation of the front-rear direction of the vehicle, a projecting distal end position of a vehicle rearward side (41b) of the cooling fins (41) is positioned further toward the inside in the width direction of the vehicle than a projecting distal end position of a vehicle front side (41a) thereof.
轮毂电动机驱动装置(1)配置在车轮(92)的轮部(W)内。轮毂电动机驱动装置(1)具备:电动机部(21),所述电动机部(21)包括使车轮旋转的电动机旋转轴及收容电动机旋转轴的电动机壳体(29);以及多个冷却翅片(41),所述多个冷却翅片(41)以从电动机壳体的车宽方向内侧端面(29e)突出的方式设置,且沿车辆前后方向延伸。在车轮(92)的前后方向的朝向与车辆的前后方向的朝向一致的状态下,冷却翅片(41)的车辆后方侧(41b)的突出前端位置位于比车辆前方侧(41a)的突出前端位置靠车宽方向内侧的位置。
