Stator core, stator unit, and motor

A stator core that is configured by stacking a plurality of core plates and that is housed inside a case of a motor, wherein:

• the plurality of core plates include a plurality of elastic protrusion-equipped core plates provided with a plurality of elastic protrusions arrayed in a circumferential direction, the elastic protrusions extending toward a radial direction outside from an outer peripheral portion of the elastic protrusion-equipped core plates and being bent in an axial direction;
• and
• the stator core is supported by the case in a state in which the plurality of elastic protrusions are in contact with an inner peripheral face of the case and elastically flexed,
• wherein the plurality of core plates include a plurality of flat protrusion-equipped core plates provided with a plurality of flat protrusions arrayed in the circumferential direction so as to extend toward the radial direction outside from an outer peripheral portion of the flat protrusion-equipped core plates,
• wherein leading end portions of the plurality of flat protrusions are arranged opposing the inner peripheral face of the case across a gap,
• wherein the plurality of elastic protrusions are bent to one side in the axial direction,
• wherein the plurality of flat protrusion equipped core plates are stacked on another side of the plurality of elastic protrusion-equipped core plates in the axial direction, and
• wherein the plurality of elastic protrusions and the plurality of flat protrusions are arranged side by side in the axial direction.
