Abstract
An armature is formed by laminating cores having through window portions which are provided in the vicinity of the surface on the slot open sides of tooth portions. The through window portions have partly opened portions, respectively. Coils are wound in slots of the laminated core. By pressing the through window portions, cut-open portions of the slot are deformed to provide outwardly curved projecting portions spaced from the coils to prevent the slipping-out of the coils.
