Claims

[Scope of utility model registration request]

A bobbin-shaped coil bobbin having a front end enlarged part and a rear end enlarged part, provided inside the coil bobbin,
A pair of saddle-shaped horizontal deflection coils, each of which has a front crossover wire section and a rear crossover wire section housed in the enlarged front end section and the enlarged rear end section, respectively, and a front crossover wire section and a rear crossover wire provided outside the coil bobbin. A deflection yoke device comprising a pair of saddle-shaped vertical deflection coils sandwiched between a front end enlarged part and a rear end enlarged part, and a core attached to the outside of the saddle-shaped vertical deflection coil. At least four pockets opening toward the rear are formed diagonally on the rear side of the part, each pocket houses a correction piece made of a magnetic material, and the opening of the pocket is connected to the front side crossing of the vertical deflection coil. A deflection yoke device characterized in that it is configured to be closed at a wire portion.
