Abstract
Two types of insulating members, i.e., end surface insulators and slot insulators are provided. On tooth portion sides of both side surfaces in the circumferential direction of tooth end surface covering portions of the end surface insulator, first cutouts recessed in the circumferential direction are provided so as to extend in the radial direction. A part axially upward of the first cutouts protrudes in the circumferential direction to form a first overhang portion, and the slot insulator is accommodated between the first overhang portions of two end surface insulators.
