PURPOSE: A deflection yoke is provided to prevent a damage of coma free by blocking the exposure of coma free mounted on the rear cover. CONSTITUTION: A deflection yoke comprises a coil separator, horizontal and vertical deflection coils, a coma free and a cover(100). The coil separator includes a screen part coupled to the screen surface of CRT, a rear cover(12) and a neck part(13) coupled to the electron gun of CRT. The horizontal and vertical deflection coils are mounted on the inside and outside of the coil separator and form a horizontal and a vertical deflection magnetic field. The coma free includes a magnet piece and coils wound to the magnet. The coma free is mounted on the rear cover(12) of the coil separator to face at the center of the neck part so as to correct misconvergence on screen. The cover(100) is mounted on the rear cover and blocks the exposure of the coma free.
