PROBLEM TO BE SOLVED: To provide a teeth structure for a motor that can increase a winding share remarkably, can achieve the reduction of manufacturing cost and efficient winding work, and by which a small and highly efficient motor can be obtained. SOLUTION: In the teeth structure for a motor that protrudes in the radial direction D of a core and has top expansion portions 4 expanded in a tapered shape to both sides of the circumferential direction R of the core at the top end portions to form semienclosed slots 8 that pass windings 7 between neighboring teeth 1, steps 5 that extend in the axial direction of a motor for the prevention of the collapse of the windings 7 are formed on the surfaces at the semienclosed slot 8 sides of the top expansion portions 4. The windings 7 can be held in a stable state on the steps 5 even if wound up to the top expansion portions 4 and the collapse of the windings 7 can be prevented, so that the share of the windings 7 can remarkably be increased.
