Zusammenfassung:PROBLEM TO BE SOLVED: To stably ensure a space between windings of an armature coil of an armature of a commutator motor. SOLUTION: When press-fitting a commutator 20 again to a predetermined position, a coil end former 40 is moved synchronously to shape a coil end 121 by the coil end former 40. While keeping the shape of a constricted part 122 of the synchronized and wound coil end, the commutator 20 is press-fitted into the predetermined position without moving a coil group as less as possible around hooks. The space between windings of an armature coil which are connected to the hooks adjoining to each other of a hook-type commutator is stably ensured. COPYRIGHT: (C)2010,JPO&INPIT
