Abstract: 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.

Abstract: An electric oil pump is coupled to a pump receptacle including an oil inflow passage and an oil outflow passage. The electric oil pump includes a motor, a pump rotor, a housing, and a check valve. The housing accommodates the motor and the pump rotor. The housing closes an opening of the pump receptacle and includes at least a fitted portion fitted into the pump receptacle. An oil compartment is formed between the pump receptacle and the housing. Oil flows into the oil compartment from the oil inflow passage when the pump rotor is rotated. The fitted portion is partially immersed in the oil collected in the oil compartment. The housing includes a suction port and a discharge port. A check valve, located in the housing, limits reversed flow of the oil from the oil compartment to the oil inflow passage.

Abstract: A motor includes a motor body, a pin, a core, and an input cam. The motor body includes a housing and an output shaft. The pin is arranged in the output shaft to extend in a direction orthogonal to a rotation axis of the output shaft. The core is pivotally supported by the pin and rotates coaxially with the output shaft. The input cam is annular and surrounds an outer circumference of the core. The input cam rotates integrally with the core. An end surface of the core closer to the housing includes a first deviated surface. The core includes an insertion portion into which the pin is inserted. When a center axis of the core is coaxial to the rotation axis of the output shaft, the first deviated surface is located at a position farther from the housing than the insertion portion.

Abstract: A brushless motor comprising: a rotor; a stator core disposed at a radial direction outside of the rotor, and a stator case. The stator core includes an outer ring shaped section, teeth sections projecting out from the outer ring shaped section toward a radial direction inside, and an inner ring shaped section extending from end portions of the teeth sections. Protruding portions are formed at the outer ring shaped section so as to project toward a radial direction outside and so as to be disposed at even intervals around a circumferential direction of the outer ring shaped section. The stator case is integrated together with the stator core by a plurality of plastic deformation portions formed at an outer peripheral portion of the stator case at locations facing towards the protruding portions, and the plastic deformation portions are disposed at even intervals along a circumferential direction of the stator case.

Abstract: A motor includes a stator, a rotor, and a case. The stator includes a stator core and windings. The rotor is provided inside the stator. The rotor includes first and second rotor cores and a field magnet. The first and second rotor cores each includes a core base and claw-shaped magnetic poles. The core bases are opposed to each other and the claw-shaped magnetic poles of the first and second rotor cores are alternately disposed in a circumferential direction. The field magnet is disposed between the core bases in the axial direction. The field magnet is magnetized in the axial direction so as to cause the claw-shaped magnetic poles of the first rotor core and the second rotor core to function respectively as first magnetic poles and second magnetic poles. At least part of an end part of the case in the axial direction is made of a non-magnetic body.
