Abut on each other to form a cone-shaped insulating frame body 11, and have first flange portions 12a and 12b on the small-diameter end side. The ribs 13a and 13b running along the mutual butting surfaces have first position regulating projections 14a and 14b projecting along the flanges 12a and 12b. Here, the projecting portion 14b has a cover portion 14c that covers the projecting portion 14a and covers the projecting portion 14a.
4c on a flat surface, a pair of half-cut ferrite cores 2
One end surfaces of a and 2b are in contact. However, the mutually butted surfaces of the two cut ferrite cores 2a and 2b are in the same plane as the mutually butted surfaces of both the bobbins 11a and 11b. Each of the half bobbins 11a and 11b has a second flange at the large diameter end as shown in FIGS. 6 and 7, and a pair of half ferrite cores 2a , 2b are in contact with each other. Further, the insulating frame 1
Conventionally, a pair of saddle-type horizontal deflection coils are incorporated inside one.

位置ずれがほぼ完全に防止される。In the deflection yoke constructed as described above, the first position regulating projection 14a of the first half bobbin 11a is provided.
Is the first position regulating projection 1 of the second half bobbin 11b.
Since both the bobbins 11a and 11b overlap and are covered by the cover portion 14c formed on the 4b, the displacement of the two half bobbins 11a and 11b in the tube axis direction is reduced. Also, even if the position shift occurs, the flat surface of the cover portion 14c regulates the end face position of the pair of half-cut ferrite cores 2a and 2b, so that the position of both the half-cut ferrite cores 2a and 2b in the tube axis direction. Displacement is almost completely prevented.
