PURPOSE: A deflection yoke is provided, in which magnet ring is arranged to have a constant tension force regardless of the insertion direction of the spacer, to thereby allow assembly work and convergence control to be easily performed. CONSTITUTION: A deflection yoke comprises a coil separator having a screen part coupled to a screen surface of CRT, a rear cover and a neck part extended from the central surface of the rear cover; a horizontal deflection coil arranged at an inner periphery of the coil separator, and which deflects electron beam in a horizontal direction; a vertical deflection coil arranged at an outer periphery of the coil separator, and which deflects electron beam in a vertical direction; a ferrite core arranged at the outer periphery of the coil separator so as to increases magnetic field; a plurality of magnet rings(20) fit to a neck part of the coil separator, and each of which rotates in a predetermined range so as to control convergence of screen; and a spacer(100) having a cylindrical body(110) fit to the outer periphery of the neck part, and a plurality of tension ribs(120) symmetrically extended from both side surfaces of the body and which have elastic force to provide tension force to each of magnet rings.
