Abstract

PURPOSE:To reduce winding distortion by providing a pair of projections which extend in the direction of a core screen side at the upper and lower ends of the core screen side and winding a vertical deflection coil including these projections. CONSTITUTION:A pair of projections 8 extend in the direction of a screen side at the upper and lower ends of the screen side of a core 4 and a vertical deflection coil 3 is wound. This can reinforce a pin cushion magnetic field on the screen side and compensate the winding distortion in the right and left ends of the screen.
