Armature and motor on which the armature is mounted
An extension part of an insulator covering a part of a coupling portion of a laminated core of an armature is inclined to the inside in the radial direction along the coupling part. A inclined face which is extended inward in the radial direction is formed in the cylindrical part of the armature. By forming the armature in an annular shape, a gap which is almost parallel or narrowed to the inside in the radial direction is formed between neighboring inclined faces. The gap is formed to be smaller than the diameter of a conductor.
