    Abstract: A stator includes a hollow cylindrical stator core, a stator coil and an outer cylinder. The stator core is comprised of a plurality of core segments that are arranged in a circumferential direction of the stator core to adjoin one another in the circumferential direction. The stator coil is mounted on the stator core. The outer cylinder is fitted on a radially outer periphery of the stator core. The outer cylinder has, at least, a protruding portion and a non-protruding portion. The protruding portion protrudes radially inward to include an abutting part that abuts the radially outer periphery of the stator core. The non-protruding portion extends, without protruding radially inward, to define a radial clearance between the radially outer periphery of the stator core and a radially inner surface of the non-protruding portion. The protruding and non-protruding portions are continuously formed in an axial direction of the outer cylinder.
