PROBLEM TO BE SOLVED: To provide a motor in which rattling of a bearing can be absorbed through a simple structure at low cost while increasing the counter electromotive force. SOLUTION: The motor comprises a housing 2, a rotor 4 supported rotatably on the housing 2 through bearings 10, 12, a rotor magnet 40 fixed to the rotor 4 through a yoke 38, and a stator 41 disposed oppositely to the rotor magnet 40 on the radial inside. The yoke 38 has an annular yoke body 62 and a yoke flange 64 extending radially from one end of the yoke body 62 and projecting farther inward than the inner circumferential surface of the rotor magnet 40.
