Abstract

PURPOSE: To attain a desired electroconductive characteristic through tight insertion only, by providing teeth on the end part of an armature coil and recesses on the inside surface of the riser part of a commutator and tightly inserting the end part of the armature coil into the riser part of the commutator so that the teeth are permanently deformed in the recesses.
CONSTITUTION: The teeth 10 are provided on the end part 2a of the armature coil 2. The recesses 6 are provided on the inside surface of the riser part of the commutator. The end part of the armature coil is tightly inserted into the riser part of the commutator so that the tips 10a of the teeth 10 are permanently deformed onto the inside surfaces of the recesses 6. The desired electroconductive characteristic and a high reliability are thus attained only by the tight insertion.
