Patent ID: 7763998

Claim:
A stator, comprising: a stator core having an annular portion defining an axial direction and a plurality of teeth which extend inward from the annular portion in the radial direction; an insulator having an annular coating portion for coating the annular portion and a plurality of tooth coating portions which extend inward from the annular coating portion in the radial direction in order to coat the respective teeth; a plurality of coils, each of which is formed of a lead wire wound around a tooth from among the teeth in such a state that the coils are separated from the teeth by the tooth coating portions, wherein the teeth include a first tooth and a second tooth around which the lead wire is wound after being wound around the first tooth; a connecting wire which includes a portion of the lead wire which extends from the first tooth to the second tooth so as to connect the coils; and an extension portion which is provided to the annular coating portion so as to extend in the axial direction, wherein the extension portion has: a distal end in the axial direction; a proximal end; a notch which extends from the distal end toward the proximal end; a bottom surface and side surfaces for defining the notch; and a radially outer surface, and the connecting wire is arranged so as to extend from the first tooth, be positioned by the bottom surface and the side surfaces, be led out from the notch in the radial direction of the extension portion, run along the radially outer surface, and be directed to the second tooth; wherein the connecting wire is one of a plurality of connecting wires, and the connecting wires include a first connecting wire which makes contact with the bottom surface and a second connecting wire which is positioned following the first connecting wire; and wherein second connecting wire is layered on the first connecting wire in the axial direction, and thus, the second connecting wire is indirectly positioned by the bottom surface.
