Abstract: A speed-reducing-gear device includes a plurality of gears, which are arranged to amplify rotational force received from an electric motor. A face width of a plurality of external teeth, which are circumferentially placed one after another in a toothed section of a final gear among the plurality of gears, varies in a rotational direction of the final gear, and the face width is measured in an axial direction of the final gear.
