Claims

[Scope of utility model registration request]

A cylindrical coil bobbin having an enlarged front end portion and an enlarged rear end portion, a pair of horizontal deflection coils provided inside the coil bobbin, a vertical deflection coil and core provided outside the coil bobbin, and a front end of the coil bobbin. In the deflection yoke device, the deflection yoke device includes a pocket provided in the enlarged portion or the rear end enlarged portion, and a plate-shaped correction piece that is inserted and housed in the pocket and corrects the deflection magnetic field generated by each of the deflection coils. A deflection yoke device characterized in that the piece is composed of a correction piece main body portion that is inserted into the pocket, and a handle portion that extends from the correction piece main body portion toward the outside of the pocket.
