Claims

[Scope of utility model registration request]

a core; a pair of saddle-shaped horizontal deflection coils and a toroidal or saddle-shaped vertical deflection coil wound along the inner surface of the core; and the horizontal deflection coil and the vertical deflection coil arranged on the inner surface of the core. A deflection yoke is constructed from a coil bobbin that maintains insulation between the coils and defines the position of each coil, and a canceller is located on the outer periphery of the deflection yoke and is wound around the outer periphery of the deflection yoke in multiple turns. A first unnecessary radiation countermeasure means consisting of a coil is provided, and a second cancel coil located outside the deflection yoke and consisting of at least a loop-wound cancel coil and a bobbin for winding the cancel coil. An unnecessary radiation countermeasure means is provided, and a position regulating means for regulating the winding position of the cancel coil of the first unnecessary radiation countermeasure means is provided on the deflection yoke or the bobbin of the second unnecessary radiation countermeasure means. Deflection yoke device.
