Claims

[Scope of utility model registration request]

In a deflection yoke device, a pair of saddle-shaped horizontal deflection coils are provided inside a coil bobbin, a pair of saddle-shaped vertical deflection coils are provided outside the coil bobbin, and a core is attached to the outside of the saddle-shaped vertical deflection coil. , a winding groove is formed in at least one of the front end face, rear end face, or inner circumferential face of the core, and the winding groove generates a magnetic field in a direction opposite to unnecessary radiation caused by leakage of the horizontal deflection magnetic field to the outside. A deflection yoke device characterized by winding a generated cancel coil.
