PURPOSE: To ensure a sufficient distance between the starting and terminating ends of a winding by fitting projections for guiding the starting end of the winding to the bottom surface of a pedestal near a high-voltage terminal erecting section, leading-out groove on a pedestal-side winding cylinder side, and the opposite side of the groove and projections for guiding the terminating end of the winding to the bottom surface of the pedestal near the high-voltage terminal erecting section and to the groove on the high-voltage terminal erecting section side from the middle section. CONSTITUTION: Projections 20, 24, and 25 for guiding the starting end of a winding are fitted to the bottom surface of a pedestal 7 on a high-voltage terminal 13a side in such a way that the projection 20 is fitted near a high-voltage terminal 13a erecting section and the terminal 25 formed in a truncated cone is fitted near a leading-out groove 11a on a pedestal- side winding cylinder 6 side, and then, the remaining projection 24 is fitted on the opposite side of the groove 11a from the line connecting the projections 20 and 25 on the terminal 13a side. Then projections 23 and 26 for guiding the terminating end of the winding are also fitted to the bottom of the pedestal on the terminal 13a side near the terminal erecting section and to a position on the terminal 13a erecting section side from the intermediate section of the erecting section and the corner of the groove on the winding cylinder 6 side. Therefore, a sufficiently long distance can be ensured between the starting and terminating ends of the winding and dielectric breakdown can be prevented.
