Abstract
A stator core includes an annular yoke portion and tooth portions, wherein an outer peripheral edge of the yoke portion is attached to an inner peripheral surface of a motor case. The yoke portion includes displacement portions displaced by receiving the radially-inward pressing force from the motor case, and deformation portions deformed according to the displacements of the displacement portions to generate tensile stress so as to form tensile stress regions through which magnetic flux passes between the tooth portions and the yoke portion or so as to counterbalance compression stress generated by the pressing force from the motor case. The displacement portions perform the displacements by attaching the yoke portion to the annular member with the interference.
