肩部の係合部１１に係合させる。Next, the operation of the above embodiment will be explained. When assembling, with the side pieces 7 of the fixture 4 slightly expanded, place the stacked iron core structure 3 on the center piece 6 with the groove 10 facing downward, while fitting the groove 10 into the protrusion 9. , placed on the central piece 6. The core structure 3 is correctly positioned by fitting the protrusions 9 into the grooves 10, and then the windings and wires 5, which have been previously wound into an oblong annular shape, are fitted onto the central leg 16. As described above, since the core structure 3 is maintained in a correctly positioned state, the above-mentioned fitting operation can be performed smoothly. Next, the other core structure 2 is fitted to the outside of the winding 5 and pushed in, pressing the both side pieces 7 of the fixture 4 inward, and bending the edges of the both side pieces 7 inward. , this edge is engaged with the engaging portion 11 of the shoulder portion of the core structure 2.
