ABSTRACT:
It is an object of the present invention to provide a commutator in which the making of the plate solder can be omitted.
A segment 21 is arranged at one end face of the axial direction of the boss 16 with an equal spacing and is fixed in an insulating manner. Each riser bar 4 is electrically connected to each segment. Each connecting plate 6 is continuously provided at each riser bar 4. A recess 5 formed at each connecting plate 6 is engaged at a projection 10 formed at the outer circumference of each ring solder 12. Each connecting plate 6 is arranged on the outer circumferential face of each segment, which is thereby electrically connected by a solder layer 13. A boss 16 surrounds each connecting plate 6 from the outside thereof in a state which makes each riser bar 4 project.
