労力と時間がかかっていた。However, the conventional iron core joint structure as described above has a problem that it takes a lot of labor and time to insert the winding. That is, when inserting the winding into the iron core, it is necessary to keep the joint open as described above. Once the bent magnetic steel plates are straightened back, not only a considerable amount of force is required, but also because the magnetic steel plates are stacked in multiple layers,
Handling the iron core was also difficult. Since it is a work with complicated movements, it is difficult to mechanize, and until now, it relied on manual labor. Therefore, it takes a lot of labor and time to insert the winding wire into the iron core.
【０００９】この発明の目的は、磁性鋼板を真直ぐに戻

Others are the same as the configuration of FIG. When the joining portion 1C is abutted from above and below in the winding, by aligning four magnetic steel plates 4 each as in the configuration of FIG. 4, the width of the recessed portion formed in the abutting portion 50 becomes wider. Therefore, the work of joining the upper and lower iron cores becomes very easy. On the contrary, if the end portions of the magnetic steel plates 4 are shifted one by one, the width of the recessed portion becomes narrower, which makes it very difficult to fit the iron cores to each other. It should be noted that the number of magnetic steel plates 4 to be aligned is generally plural, but this number is preferably several to ten, and it is easy to fit them in the abutting portion 50, and the magnetic resistance is too large.
