Abstract: A stator core includes: an assembled stator core formed of annularly arranged, divided stator cores; a fixing member disposed at an outer circumferential surface of the assembled stator core and capable of pressing the divided stator cores inward in a radial direction of the assembled stator core to annularly arrange and thus fix the divided stator cores; and a weak portion provided between the divided stator cores and the fixing member and deformable by a force exerted from the fixing member to press the divided stator cores.
