Claim:
A stator of an electric rotating machine comprising: a stator core constituted of a plurality of split cores joined to one another in a ring; a plurality of phase windings wound around the stator core; and an outer casing to an inner periphery of which an outer periphery of the stator core is fitted with clamping margin therebetween; wherein the outer casing is provided with a brim including at least two brim portions at least at one of axial ends thereof, the brim portions being spaced from each other in a circumferential direction of the outer casing and projecting in a direction radially outwardly from a center axis of the outer casing, wherein the clamping margin is not uniform along the circumferential direction of the outer casing, a value of the clamping margin at portions of the outer casing in each of which the brim portion is provided is smaller than at other portions of the outer casing in each of which the brim portion is not provided, and the inner periphery of the outer casing is expanded radially outwardly at the brim portions, whereby an inner diameter of the outer casing is greater at portions of the outer casing in each of which the brim portion is provided than at other portions of the outer casing in each of which the brim portion is not provided.
