示すようにはめ合わせると第15図に示す状態となる。Prior Art FIG. 10 shows a saddle-shaped deflection coil of a deflection yoke mounted on a cathode ray tube. One way to make such a saddle-shaped coil is to use a pair of molds shown in Figure 14, and with these two molds joined together as shown in Figure 15, a special mold is used for this mold. There is a method of winding the wire using a winding machine, and before removing the resulting wire bundle from the mold, an electric current is passed through the wire to generate heat and fix each wire. In Figure 14,
12 is a first mold, and 13 is a second mold, and when they are fitted together as shown by the arrows, the state shown in FIG. 15 is obtained.

の電流を流す事によって発熱させる。In FIG. 15, 14 is a wire guide member, and 15 is a wire drawn out from the wire guide member. The wire is wound around the mold by rotational movement of the wire guide member 14 around the mold in a single direction, the direction of arrow C. To explain the steps below, first, the first mold 12 and the second mold 13 are fitted together as shown in FIG. 15. Next, the end of the wire pulled out from the wire guide member 14 is fixed to something other than the mold. Next, the electric wire guide member is rotated. FIG. 11 shows only the coil in the winding process. After winding the wire a predetermined number of times, the wire is cut and the beginning and end of the winding are connected to a power source and a predetermined current is applied to generate heat.

コイルに歪みが生じてくる事となる。Problems to be Solved by the Invention The conventional method as described above fixes the end of the wire,
The wire guide member is simply wound in one direction while being turned. By the way, when winding the wire, some tension is applied to the wire, and in that state the wire is wound only in one direction. However, there is a force in the wire that causes it to shrink, and that force does not disappear even after the wire has been wound. This remains as stress in the completed coil, and this stress causes distortion in the completed coil as shown in FIGS. 12 and 13.
本発明は以上の課題をに鑑みてなされたものであり、完
成後に歪が生じる事がない偏向コイルの巻線方法を提供
