Beschreibung
Zusammenfassung:	A stator is equipped in a housing. A coil is equipped to the stator to produce a magnetic flux when supplied with an electricity. A rotor is formed of a magnetic material and is rotational in the stator. The rotor includes a rotor core, a salient pole, and an accommodation cavity portion. The salient pole is projected from the rotor core toward the stator. The accommodation cavity portion extends in the salient pole along the thickness direction. An expansive member is formed of a magnetic material, which has a thermal expansion coefficient different from a thermal expansion coefficient of the rotor. The expansive member is equipped in the accommodation cavity portion. The expansive member expands in response to increase in a temperature.
