Further, it goes without saying that the configuration of the motor 10, which is a DC motor, is not limited to the configuration of the above embodiment. Therefore, for example, the brush holder 42 that holds the shape of the yoke 12 and the power supply terminal 52 (brush 50).
The holding structure of the magnets 22A and 22B can be appropriately changed, and the power supply terminal 52 may be held in an elastically deformed state. The pair of magnets 22A and 22B are provided on the inner surface of a substantially cylindrical yoke with one circumferential end of the magnets 22A and 22B. Each of the engaging portions and one spring 24 engages with the magnet 22.
