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: 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.
