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).
