PROBLEM TO BE SOLVED: To provide a motor with a slowdown mechanism in which the durability of a one-way clutch can be enhanced without deteriorating the dimensional precision or the moldability of a clutch housing. SOLUTION: At the bottom on the inside of a clutch housing 33a, a thrust plate 33e made of a material of higher hardness than that of the clutch housing 33a is provided, and a pair of second steel balls 33f rolling with respect to the thrust plate 33e is provided. Since a thrust load from a motor shaft 24 is received by the thrust plate 33e of high hardness, the bottom inside the clutch housing 33a can be prevented from being worn out. Since the clutch housing 33a does not require the quenching nor the molding of a high hardness material, the durability of the one-way clutch 33 can be enhanced without deteriorating the dimensional precision or the moldability of the clutch housing 33a.
