低減することができる。Effects of the C Design As described above, according to the present invention, the end of the bobbin facing the slip-ring support side is engaged so that the vicinity of the starting end of one coil and the vicinity of the terminal end of the other coil are separated from the rotating shaft. Since an engagement groove is provided for mating, it is possible to connect the starting end of one coil and the terminal end of the other coil to the connecting piece in a tensioned state while avoiding contact with their rotating shafts. Insulating parts such as insulating tubes that were previously used are no longer necessary, and the number of parts can be reduced.

り、その作業能率の向上に大いに寄与し得る。 Further, a protrusion for commonly winding the terminal end of the one coil and the starting end of the other coil is protruded from the bobbin, and the terminal end of the one coil and the starting end of the other coil are wound at this protruding part. Since the respective winding parts are soldered to each other, by soldering both the winding parts to each other while the terminal end of the one coil and the starting end of the other coil are wound and held on the common protrusion, The terminal end of one coil and the starting end of the other coil can be easily connected, and there is no need to connect the terminal end of one coil and the starting end of the other coil in the air as in the past. Coupled with the effect that the special provision of the recessed portion eliminates the need to provide insulating parts such as an insulating tube, the overall coil connection work becomes extremely easy and can greatly contribute to improving the work efficiency.
