PROBLEM TO BE SOLVED: To provide an in-wheel motor drive capable of supplying lubricant of requisite amount of discharging from an oil pump even under a slow speed operation or a rearward driving operation.SOLUTION: An inner rotor of an oil pump 40 is provided with a gear side pump driving shaft 51 driven in rotation by a rotating force of a speed reducer B and an auxiliary pump driving shaft 52. An auxiliary electric motor 54 is connected to the auxiliary pump driving shaft 52. One-way clutches 60a, 60b allowing rotation of the inner rotor in a direction where lubricant is sucked from a lower part of the casing and shutting off a rotation of the inner rotor in a reverse direction are arranged between a speed-reducer side motor drive shaft 51 and the inner rotor.SELECTED DRAWING: Figure 2

    【課題】低速時やバック走行時でもオイルポンプから必要な吐出量の潤滑油を供給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】オイルポンプ40のインナーロータに、減速機Bの回転力によって回転駆動するギア側ポンプ駆動軸51と、補助ポンプ駆動軸52とを設け、補助ポンプ駆動軸52に補助電動モータ54を接続し、減速機側モータ駆動軸51とインナーロータ間に、ケーシングの下方から潤滑油を吸引する方向へのインナーロータの回転を許容し、逆方向へのインナーロータの回転を遮断する一方向クラッチ60a、60bを設けたものである。【選択図】図2
