<p>PROBLEM TO BE SOLVED: To provide an armature core by which reduction in roundness can be suppressed.SOLUTION: A stator core 10 comprises: a plurality of divided cores 12 circularly arrayed; and a shaft 14 press-fitted into an axial center part of the plurality of circularly arrayed divided cores 12. Further, the divided core 12 comprises: a teeth part 30; and a connecting part 34 provided for an inner side in a radial direction of the teeth part 30. Further, a fitting protrusion part 36 is provided for an end part on one side in a circumferential direction of the connecting part 34, and a fitting recess part 38 is provided for an end part on the other side in a circumferential direction of the connecting part 34. Furthermore, in the state where the shaft 14 is press-fitted into the axial center part of the plurality of divided cores 12, the fitting protrusion part 36 and the fitting recess part 38 contact at two positions of an outer contact part C1 and an inner contact part C2, and the outer contact part C1 and the inner contact part C2 are arranged on a line L3 extending outward in a radial direction from the axial center of the shaft 14.</p> |
