PURPOSE: A deflection yoke is provided to prevent the magnetic saturation of inner arms, thereby embodying stable deflection of electron beam and enhancing image quality. CONSTITUTION: A deflection yoke comprises a coil separator(21), a vertical deflection coil(24), inner arms(25) and a magnetization unit(40). A horizontal deflection coil(22) is seated on the internal surface of the coil separator(21). The vertical deflection coil(24) is disposed on outer surface of the coil separator together a ferrite core. The inner arms(25) are disposed by 180 degree. on middle outer surface of the coil separator to barrel-magnetize the vertical magnetic field through the vertical deflection coil. The magnetization unit(40) strengthens the magnetic saturation of the inner arms.
