In a vehicle power unit, a drum rotary shaft member on one side of a shift drum is provided with a driven gear. A case side wall on one side of an engine crankcase supporting the drum rotary shaft member is covered by a case cover member in opposing relation thereto. A shift motor is mounted to the case cover member, with a driving gear thereof directed to protrude toward the case side wall. A speed reducing gear train has gear shafts and provides a multiplicity of speed reduction stages for transmitting power from the driving gear to the driven gear. The speed reducing gear train is arranged with both ends of its gear shafts thereof supported on the case side wall and the case cover member, respectively. Such arrangement provides a vehicle power unit for a fast and smooth shift by an electric motor.
