PROBLEM TO BE SOLVED: To provide a stator which can be attached easily while reducing the size. SOLUTION: The stator 20 comprises a stator core 23 equipped with a ring-shaped annular portion 21 and a plurality of teeth 22 extending radially from the annular portion 21, and a cylindrical yoke 24 having an inner circumferential surface 24a fixed with the outer diameter side end 22a of the teeth 22 and an outer circumferential surface 24b composed of a magnetic body forming the outer circumferential surface of a motor. The outer circumferential surface 22b at the outer diameter side end 22a of the teeth 22 is a curved surface extending along the inner circumferential surface 24a of the yoke 24 and the stator core 23 is secured to the yoke 24 by press fitting the outer circumferential surface 22b at the outer diameter side end 22a to the inner circumferential surface 24a of the yoke 24. A recess 27 extending in the axial direction is formed in the circumferential center at the outer diameter side end 22a of the teeth 22. A protrusion 28 engaging with the recess 27 is provided on the inner circumferential surface 24a of the yoke 24 to project therefrom and extend in the axial direction. COPYRIGHT: (C)2007,JPO&INPIT |
