PROBLEM TO BE SOLVED: To prevent second and succeeding wires from being disordered under influence of a lead-out wire.SOLUTION: A stator 4 includes a cylindrical yoke part 6, a rectangularly-sectioned teeth part 7 which projects radially from the yoke part 6, a restriction wall part 15 which projects axially from the yoke part 6 and is provided with a wire lead-out part 17, and a coil 8 which has a wire 14 arrayed and wound while positioned by the wire lead-out part 17. Peripheral surfaces 6a of the yoke part 6 on both sides of the teeth part 7 are shifted radially in position when the axial direction is viewed from the side where the wire 14 is led out, and then a first edge part 21 where the wire begins to be wound between two edge parts 20 of the teeth part 7 extending radially is longer than a fourth edge part 24 where the wire puts and end to winding. |
