PURPOSE: A deflection yoke is provided to correct mis-convergence at the screen in a detailed manner by improving the structure of the comma free member arranged at the rear cover of the coil separator. CONSTITUTION: A deflection yoke comprises a coil separator including a screen part coupled to a screen surface of a CRT, a rear cover and a neck part extended from the central surface of the rear cover; a horizontal deflection coil and a vertical deflection coil arranged at the inner surface and the outer surface of the coil separator, respectively, and which generate deflection magnetic field for deflecting electron beam in horizontal and vertical directions; and a comma free member(100) which is arranged at the rear cover of the coil separator in such a manner as to oppose with each other centering from the neck part. The comma free member corrects mis-convergence at the screen, and has magnet pieces(120) wound with coils(110) and arranged at both ends of the comma free member, and an auxiliary magnet piece(130) extended between magnet pieces, wherein the auxiliary magnet piece is not wound with coil.
