Beschreibung
Zusammenfassung:	The present invention can provide a pinion-equipped motor that has a shaft provided with a pinion having a perfect tooth shape portion functioning as a gear, wherein to shorten the length of the pinion in the axial direction, the perfect tooth shape portion of the pinion can be offset to the proximal side of the shaft. In this pinion-equipped motor that has a shaft provided with a pinion on the distal side, the pinion has: a base portion that is mounted on the shaft; a perfect tooth shape portion that has an outer diameter equal to or smaller than that of the shaft and functions as a gear; and an imperfect tooth shape portion which is provided between the base portion and the perfect tooth shape portion, the length in the shaft axial direction of which is equal to or smaller than that of the perfect tooth shape portion in said direction, and which does not function as a gear.
