The horizontally defection coils 1, the insulation frame, the vertical deflection coil the ferrite core are configured in the deflecting coil provided by the invneiton. The multiple elastic juts on the outer wall 4a of the small-bore part for holding the ferrite core are setup vertically on one outer wall of the small-bore part of the insulation frame 20. Thus, the ferrite core is positioned in the vertical axis Y, keeping the optimal position. The outer wall of the small-bore part of the ferrite core possesses the conic section with the diameter being reduced near the terminal of the small-bore part. The elastic juts holds the said conic section 4e. Thus, the ferrite core is positioned in the tube axis, keeping the optimal position. The above result can realize the color cathode ray tube with YH cross type error focusing being reduced. |
