PROBLEM TO BE SOLVED: To provide a motor with a decelerator mechanism in that improves the molding performance of a gear case, by abandoning the use of a circular cylindrical portion to be molded integrally with the gear case, and a yoke can be coupled with the gear case so that shaft centers will not be shifted from each other. SOLUTION: An inner yoke 14, in which its one end engages with the inner side of an outer yoke and the other end protrudes toward the gear case 12, is provided, so that an protrusion portion 14a of the inner yoke 14 engages with the inside of a flange portion 12c of the gear case 12. With this configuration, use of a circular cylindrical portion, integrally molded with a gear case in a conventional technique, is abandoned, and the molding performance of the gear case can be improved. Furthermore, the inner yoke 14, provided differently from the gear case 12, can couple the outer yoke with the gear case 12 so that the mutual shaft centers will not shift from each other.
