Abstract
A rotary electric machine includes a rotor including a shaft, a stator disposed around the rotor, a housing configured to house the stator, a first annular member disposed on the stator and having first recesses disposed in a circumferential direction, a second annular member disposed on the housing and having second recesses disposed in the circumferential direction, and balls interposed between the first annular member and the second annular member. Each ball is disposed in both of each of the first recesses and each of the second recesses. The first annular member, the second annular member, and the balls constitute a coupling mechanism configured to couple the housing and the stator to each other. A backlash in a radial direction in the coupling mechanism is narrower than a backlash in the circumferential direction in the coupling mechanism and narrower than a backlash in an axial direction in the coupling mechanism.
