ABSTRACT:
An electrical motor includes a commutator attached to one side of an armature in an axial direction, and a cover structure member attached to the other side of the armature. The cover structure member includes a cover and plural terminals protruding from an outer peripheral portion of the cover toward the armature. In the electrical motor, by attaching the cover structure member to the armature, the other side of the armature in the axial direction is covered by the cover, and the terminals of the cover structure member are fitted to terminals of coils of the armature. Generally, the cover structure member is made of metal. Therefore, the cover structure member is attached to the armature to have a clearance between a through hole portion of the cover and a shaft, so that the cover is electrically insulated from the shaft.
