Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a planetary gear device capable of reducing rotation unevenness caused by a concentricity error between an internally toothed gear and a sun gear which is provided coaxially with a drive shaft and between the internally toothed gear and a carrier.SOLUTION: A drive motor 111 is positioned and fixed to a stud 150 which is supported by the body rear side plate 164 of a copier 500, and disposed coaxially with an internally toothed gear 140 and a first-stage sun gear 123 which is formed coaxially with the motor shaft 112 of a drive motor 111. A seat surface 142 is then provided at the output side of the internally toothed gear 140, and the seat surface 142 and the body rear side plate 164 of the copier 500 are positioned and fixed by screws. The side of the drive motor 111 in the internally toothed gear 140 is made into free end with no support structure.
