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: An object of the present invention is to maintain the tightening load between a casing and a stator appropriately even when used in a high temperature environment.
A rotary electric machine includes a rotor, a stator made of an iron-based member and provided on an outer periphery of the rotor, and a casing that is made of an aluminum alloy member, houses the rotor and the stator, and fixes the stator by bringing an inner peripheral surface into contact with an outer peripheral surface of the stator. The casing is permanently grown before the stator is fixed in the casing.

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: 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.
