Claim Text:
1. A stator for a rotating electric machine, the stator comprising: a hollow cylindrical stator core comprised of a plurality of stator core segments that are arranged in a circumferential direction of the stator core to adjoin one another in the circumferential direction; a stator coil mounted on the stator core; and an outer cylinder fitted on a radially outer surface of the stator core, wherein the stator core has a recess formed in the radially outer surface thereof, the recess having an engaging wall surface that extends in both an axial direction and a radial direction of the stator core, the outer cylinder has a plurality of first slits and a second slit, all of which radially penetrate the outer cylinder to connect radially outer and inner surfaces of the outer cylinder, the first slits extend in the circumferential direction of the stator core and are spaced from one another in the axial direction of the stator core, the second slit extends in the axial direction of the stator core to connect the first slits, the outer cylinder also has a fastening portion for fastening the outer cylinder to the stator core, the fastening portion being formed to be partially surrounded by the first and second slits, the fastening portion is bent radially inward to have a second slit-side end part thereof received in the recess of the stator core, and the second slit-side end part of the fastening portion has a distal end engaging with the engaging wall surface of the recess of the stator core.
