In the rotary electric machine, a cylinderof a ring componentis formed in such a way that a fitting outer surfaceof the cylinderof the ring componentis fitted to a fitting inner surfaceof a first housing; a clearance value between the fitting outer surface of the cylinder and a fitting inner surface of the first housing is lower than a clearance value between an outer surface, in which the fitting outer surface is excepted, of the cylinder and an inner surface, in which the fitting inner surface is excepted, of the first housing; and a position in a diameter direction of a stator corefacing to the first housing is set by above-described fitting process.

Rotary electric machine

In a rotary electric machine, a cylindrical stator core holding frame is cantilevered on a housing. A cylindrical stator core is fitted together and held inside the stator core holding frame. The stator core holding frame includes: a flange portion that is fixed to the housing; and a frame cylindrical portion that is coupled to the flange portion, and that holds the stator core. A thickness of the flange portion is greater than a thickness of the frame cylindrical portion.
