The invention provides a motor driving device for a vehicle, being characterized in that a motor rotating shaft and an input gear shaft are embedded and combined through splines, and an oil supply nozzle part for supplying lubricating oil into the input gear shaft is simply and reliably fixed on a shell. In the motor driving device for the vehicle, a motor rotating shaft (25) of an electric motorpart and an input gear shaft (30) of a speed reducer part are coaxially connected through spline embedding, and an oil supply nozzle part (85) for supplying lubricating oil to the input gear shaft (30) is arranged on the outer plate side of the input gear shaft (30). The oil supply nozzle part (85) has a nozzle part (85a) inserted into the input gear shaft (30) and an elastic support part (85g) protruding radially outward along the outer circumference of the main body part, and is inserted into an oil supply nozzle part attachment hole (72d) provided in a reduction gear shell (22) to which theoil supply nozzle part (85) is attached. The elastic support part (85g) is fixed to a mounting hole (72d) for the oil supply nozzle part, and lubricating oil is supplied from an oil reservoir part (22d) to the oil supply nozzle part (85).

    本发明提供一种车辆用马达驱动装置,其将马达旋转轴和输入齿轮轴之间通过花键嵌合结合,其中,将向输入齿轮轴内供给润滑油的供油喷嘴部件简单且可靠地固定于外壳。在电动马达部的马达旋转轴(25)和减速器部的输入齿轮轴(30)之间通过花键嵌合同轴连结的车辆用马达驱动装置中,在输入齿轮轴(30)的外板侧配置有向输入齿轮轴(30)内供给润滑油的供油喷嘴部件(85),供油喷嘴部件(85)具有插入到输入齿轮轴(30)的喷嘴部(85a)和沿主体部的外周向径向外侧突出的弹性支承部(85g),供油喷嘴部件(85)插入到设置于减速器外壳(22)的供油喷嘴部件用安装孔(72d),通过弹性支承部(85g)固定于供油喷嘴部件用安装孔(72d),从贮油部(22d)向供油喷嘴部件(85)赋予润滑油。
