Claims

[Scope of utility model registration request]

An annular core formed by joining a pair of semi-annular cores, a pair of saddle-shaped horizontal deflection coils and a pair of saddle-shaped vertical deflection coils wound along the inner surface of the core; Connecting in series to the deflection coil a pair of cancel coils that generate a magnetic field opposite to unnecessary radiation leaking from the core to the outside in the horizontal deflection magnetic field generated by the horizontal deflection coil, and deflecting the cancel coil. 1. A deflection yoke device, characterized in that the core is located on or near the X-axis of the yoke and is pre-wound in a toroidal shape around the core except for the joint portion of the core.
