特徴とする偏向ヨーク装置。 a core, a pair of saddle-shaped horizontal deflection coils and a pair of toroidal or saddle-shaped vertical deflection coils wound along the core, and arranged on the inner surface of the core between the horizontal deflection coil and the vertical deflection coil. A deflection yoke is constituted by a coil bobbin that maintains the insulation of the coil and defines the position of both coils,
Outside the deflection yoke, an unnecessary radiation countermeasure means consisting of a cancel coil wound at least in a loop is attached and fixed, the center of which is located on or near the Y axis of the deflection yoke, and the cancel coil is provided with the above-mentioned A horizontal deflection current supplied to the horizontal deflection coil or a current synchronized with the horizontal deflection current is passed to generate a magnetic field opposite to unnecessary radiation leaking to the outside from the deflection yoke among the horizontal deflection magnetic field generated by the horizontal deflection coil. Also, a deflection yoke device characterized in that the cancel coil is constructed using a wire or a plurality of thin wires to prevent heat generation due to high frequency current.
