Included are a pair of insulators arranged on axial end surfaces of a split core, and an insulating film attached to lateral side surfaces of the tooth part, for insulating the split core from a coil wound around the tooth part. Each insulator includes projections projecting further than a tooth front end part in the circumferential direction, slits which are formed in the respective projections to a corresponding axial end surface side of the tooth front end part and into which the insulating film is inserted, and ribs formed, on an end surface side in the circumferential direction, in the respective projections. The insulating film inserted into the slits is folded back to a back yoke part side with the ribs interposed therein, and fixed by being interposed between the ribs at tip portions of projections of adjacent insulators. Accordingly, the insulating film can be assuredly fixed and prevented from escaping from a slot. |
