Abstract: A rotating electric machine according to an embodiment of the present invention includes a rotor; a stator; an insulator; and a coil. The rotor rotates about a first axis. The stator includes teeth projecting toward the rotor. The insulator is attached to each of the teeth. The coil is wound around the insulator. The insulator includes a pair of side surface portions that are mounted on the teeth to generate a biasing force against the teeth in a twisting direction with respect to a direction of the first axis.

Abstract: [Object] To provide an electronic apparatus capable of inhibiting a failure due to dropping of a screw from occurring.
[Solving Means] An electronic apparatus 100 according to an embodiment of the present invention includes: a casing 10; a cover portion (case cover 20); a circuit board 22; a screw member 80; and a facing member (holding member 60). The cover portion has a first surface and a second surface and is to be attached to an opening portion 11 of the casing 10, the first surface including a screw hole 203 and facing the casing 10, the second surface being opposite to the first surface. The circuit board 22 is to be disposed on the first surface. The screw member 80 includes a head portion 81 and a shank 82 and fixes the circuit board 22 to the cover portion, the head portion 81 engaging with the circuit board 22, the shank 82 including a groove 82s and passing through the circuit board 22, the groove 82s being screwed into the screw hole 203. The facing member is to be disposed inside the casing 10 and faces the head portion 81 with a distance (L1) smaller than a length (L2) of the shank 82.

Abstract: The rotor includes a drive shaft, a first rotor core unit, and a second rotor core unit. The first rotor core unit is configured from a first iron core material having a through-hole into which the drive shaft is inserted, and a plurality of first permanent magnets, and includes a first reference surface at which the first iron core material is flush with or protruding further than first permanent magnets. The second rotor core unit is configured from a second iron core material having a through-hole into which the drive shaft is inserted, and a plurality of second permanent magnets, and has a second reference surface at which the second iron core material is flush with or protruding further than second permanent magnets, the second rotor core unit being laminated in an axial direction on the first rotor core unit such that the first reference surface and the second reference surface contact each other.

Abstract: An object of the present invention is to hold a holding member appropriately in a casing.
A rotary electric machine includes a rotor having a drive shaft, a stator provided on an outer periphery of the rotor, a bearing B2 that rotatably supports the drive shaft, a holding member that contains an aluminum alloy member and holds the bearing, and a casing that houses the rotor, the stator, the bearing, and the holding member. The casing is made of a member that does not grow permanently or an aluminum alloy member that is permanently grown when the holding member is fixed to the casing. The holding member is in a state before permanent growth before being fixed in the casing, and the holding member grows permanently to be fixed more firmly to the casing.
