A winding 24 is fixed via 2. The same number of terminals 28 as the terminals 26 of the winding 24 are provided on the outer periphery of the wiring board 16, and are attached to a terminal block 301 made of an insulating material with rivets 32. The other configurations are also the same as the conventional example, but because the unfolded shape for removing the wiring board 16 from the rectangular board is different, the ends 40 of the mounting legs 18 protrude from the disc surface of the wiring board 16, and the disc surface The structure has a loophole. FIG. 4 shows the developed shape of the wiring board of the electrical conductor according to the present invention.
