PROBLEM TO BE SOLVED: To provide a geared motor which has high strength and in which a positioning protrusion capable of arranging an output gear with high positional precision can be formed in a resin case when the resin case is loaded in an apparatus. SOLUTION: This geared motor 1 comprises a stepping motor 2, a speed reducing gear train 7 for transmitting the rotation of the stepping motor 2, the output gear 3 for outputting the transmitted rotation to the outside though the speed reducing gear train 7, and the resin case 4 fixed to a metal rotating center shaft 31 mounted so as to rotate the output gear 3 and in which the speed reducing gear train 7 is stored. In the rotating center shaft 31 of the output gear 3, its lower end protrudes as the positioning protrusion 30 outward from the resin case 4. COPYRIGHT: (C)2004,JPO
