PURPOSE: A deflection yoke of a cathode ray tube is provided to improve sensitivity of a second quadruple electrode convergence yoke and reduce manufacture cost. CONSTITUTION: A deflection yoke of a cathode ray tube comprises a first quadruple electrode convergence yoke and a second quadruple convergence yoke. The first quadruple electrode convergence yoke changes a distance between an R beam and a B beam of electron beams emitted from an electron gun. The second quadruple electrode convergence yoke corrects mis-convergence due to the first quadruple electrode convergence yoke. The first quadruple electrode convergence yoke is mounted to a neck of the deflection yoke. The second quadruple electrode convergence yoke is mounted to a funnel cone(90) by reference protrusions(91) that are formed at an aperture of the deflection yoke and the funnel cone(90) and fixed by a tape and an adhesive.
