PROBLEM TO BE SOLVED: To provide a motor capable of excellently balancing detent torque.SOLUTION: A rotor 21 is accommodated within a motor case in such a manner that a first rotor core 31 (core base 31a) is positioned closer to an end frame (lid part) in an axial direction and a second rotor core 32 (core base 32a) is positioned closer to a bottom part 13a of a yoke housing 13. The second rotor core 32 is formed from a metal material with a lower carbon content than the first rotor core 31 (low carbon steel), such that the second rotor core 32 is more hardly magnetically saturated than the first rotor core 31. |
