摘要： A metal pump housing includes a shaft support hole for supporting a middle part of a rotary shaft. The rotary shaft includes a first end on which a pump operating portion is provided and a second end on which a motor rotor is provided. A metal motor case is fixed to a part of the pump housing that is at a side of the second end. The motor case accommodates a motor section including a motor stator and a motor rotor. A plastic circuit case member is fixed to a part of the motor case that is opposite to the part to which the pump housing is fixed. A circuit substrate for controlling the motor section is fixed to the circuit case member and is separate from the motor case.

摘要： A driving device includes a rotor unit including a rotation shaft, a fluid supplying portion, and a motor rotor, a housing that rotatably supports the rotation shaft, a stator case accommodating a motor stator and a motor rotor. The motor rotor includes a consequent pole rotor including a motor rotor core and a plurality of the magnets arranged along a circumferential direction of the motor rotor core. The magnets form a plurality of magnetic pole portions that serve as primary magnetic poles. The motor rotor core includes portions located between adjacent ones of the magnetic pole portions in the circumferential direction. The portions form magnetic-pole-forming portions that serve as secondary magnetic poles. The motor unit includes a magnetization inhibiting portion formed to inhibit magnetization of the fluid supplying portion. The support portion of the housing comprises a nonmagnetic metal.
