Longitudinal lead bars extend in electrically insulated state in longitudinal lead grooves provided in an outer circumferential surface of the collector shaft and are connected to ring through studs. Radial lead bars are located at a collector shaft-side end portion of the main shaft and connect at their inner end portions to the bands. And, both ends of conductive longitudinal studs inserted into longitudinal through holes at a main shaft-side end portion of the collector shaft are connected to outer end portions of the radial lead bars and to the longitudinal lead bars.
