ABSTRACT:
A deflection yoke includes a horizontal deflection coil, a vertical deflection coil, an insulating frame made of an insulating material, a deflection adjusting plate attached to an outer circumferential surface of the insulating frame, and a ferrite core covering at least a part of an outer circumference of the insulating frame. The deflection adjusting plate is fixed to the outer circumferential surface of the insulating frame, under the condition of being surrounded by a high-soft resin material with a hardness of 10 to 60. Because of this, even when the deflection adjusting plate vibrates during driving, the deflection adjusting plate does not directly bump into the insulating frame, so that the noise generated by the deflection yoke can be reduced significantly.
