To easily and surely fix an oil supply nozzle member for supplying a lubricant to an input gear shaft, to a housing in a motor driving device for a vehicle in which a motor rotating shaft and the input gear shaft are connected by spline-fitting.SOLUTION: In a motor driving device for a vehicle in which a motor rotating shaft 25 of an electric motor portion and an input gear shaft 30 of a speed reducer portion are coaxially connected by spline-fitting, an oil supply nozzle member 85 for supplying a lubricant into the input gear shaft 30 is disposed at an outboard side of the input gear shaft 30, the oil supply nozzle member 85 has a nozzle portion 85a inserted to the input gear shaft 30, a main body portion, and an elastic supporting portion 85g disposed on an outer periphery of the main body portion in a manner of projecting to a radial outer side, and the oil supply nozzle member 85 is inserted to an oil supply nozzle member mounting hole 72d formed on a speed reducer housing 22, and fixed to the oil supply nozzle member mounting hole 72d by the elastic supporting portion 85g to supply the lubricant from an oil reservoir portion 22d to the oil supply nozzle member 85.SELECTED DRAWING: Figure 3

    【課題】 この発明は、モータ回転軸と入力歯車軸との間がスプライン嵌合により結合された車両用モータ駆動装置において、入力歯車軸内に潤滑油を供給する油供給ノズル部材を簡単に且つ確実にハウジングに固定する。【解決手段】 電動モータ部のモータ回転軸25と減速機部の入力歯車軸30との間がスプライン嵌合によって同軸に連結されている車両用モータ駆動装置であって、入力歯車軸30のアウトボード側に、入力歯車軸30内に潤滑油を供給する油供給ノズル部材85が配置され、油供給ノズル部材85は、入力歯車軸30に挿入されるノズル部85aと本体部と本体部の外周に径方向外側に突出する弾性支持部85gとを有し、油供給ノズル部材85は、減速機ハウジング22に設けられた油供給ノズル部材用取付穴72dに挿入され、弾性支持部85gにより油供給ノズル部材用取付穴72dに固定され、油溜部22dから油供給ノズル部材85へ潤滑油が与えられる。【選択図】 図3
