Abstract
A stator core that is configured by stacking plural core plates and that is housed inside a case of a motor. The plural core plates include an elastic protrusion-equipped core plate provided with plural elastic protrusions arrayed in a circumferential direction. The elastic protrusions extend toward a radial direction outside from an outer peripheral portion of the elastic protrusion-equipped core plate and are bent in an axial direction. The stator core is supported by the case in a state in which the plural elastic protrusions are in contact with an inner peripheral face of the case and elastically flexed.
