Abstract
A stator of a motor includes a plurality of magnetic bodies stacked in a direction of a central axis (X), a case configured to hold the plurality of magnetic bodies, a cover configured to cover the case, and a pillar including a guiding part configured to guide the plurality of magnetic bodies in the direction of the central axis (X). The plurality of magnetic bodies include a guided part guided by the pillar. The pillar includes an outer peripheral surface including positioning parts. The positioning parts determine relative positions of the case and the cover in an axial direction.
