PROBLEM TO BE SOLVED: To provide a motor with a slowdown mechanism in which the "shake" of a one-way clutch can be suppressed without lowering the attachment workability of a bearing. SOLUTION: A tip side bearing 44b for supporting a motor shaft 24 rotatably between a worm and a one-way clutch 33, and a clutch bearing 44a for supporting the one-way clutch 33 rotatably are press-fitted in a worm containing section 42 of a gear case 40. Consequently, a columnar section 31 and the one-way clutch 33 can be rotatably supported independently by the respective bearings 44b, 44a. Since the axial length of each bearing 44a, 44b can be shortened, the deterioration of attachment workability to the worm containing section 42 can be suppressed and the rotation of the one-way clutch 33 can be stabilized by suppressing the "shake" of the one-way clutch 33 effectively.
