PROBLEM TO BE SOLVED: To provide an in-wheel motor drive unit for a steering wheel which does not sacrifice a steering angle, and does not need to widen a wheel house.SOLUTION: A motor part (121) of an in-wheel motor drive unit (110) for a steering wheel has: a cylindrical first casing (125) which forms a contour of the motor part at one side in an axial line (M) direction; a second casing (126) which forms a contour of the motor part at the other side in the axial line direction, and in which an outside diameter of the other end (128) in the axial line direction is smaller than an outside diameter of one end in the axial line direction; abutment faces (125f, 126f) which are arranged at the other end of the first casing in the axial line direction, and one end of the second case in the axial line direction, and made to abut on each other; and a stator (124) which extends to the axial line direction, is arranged in the first casing at one end, and arranged in the second casing at the other end.SELECTED DRAWING: Figure 1
【課題】転舵角が犠牲にならず、またホイールハウスを広くする必要がない、転舵輪のためのインホイールモータ駆動装置を提供する。【解決手段】転舵輪用インホイールモータ駆動装置(110)のモータ部(121)は、モータ部の軸線(M)方向一方側の外郭をなす円筒状の第1ケーシング(125)、モータ部の軸線方向他方側の外郭をなし軸線方向他方端(128)の外径が軸線方向一方端の外径よりも小さい第2ケーシング(126)、第1ケーシングの軸線方向他方端および第2ケーシングの軸線方向一方端にそれぞれ設けられて互いに突き合される突合面(125f,126f)、および軸線方向に延びて一方端が第1ケーシングの内部に設置されるとともに他方端が第2ケーシングの内部に設置されるステータ(124)を有する。【選択図】図1
