PURPOSE: A deflection yoke and a cathode-ray tube device are provided to correct the misconvergence on horizontal lines displayed in the upper and lower parts on its screen by the rasters of side electron beams without seriously affecting vertical deflection sensitivity, and also without the changing of horizontal trapezoid distortion. CONSTITUTION: A pair of saddle-type vertical deflection coils(12R,12L), an auxiliary vertical deflection coils(6a,6b), the first pair of correction coils(2R,2L), and the second pair of correction coils(3R,3L) are sequentially connected in series. Further, resistors(13a,13b) and a variable resistor(14a) are connected in parallel with the pair of saddle-type vertical deflection coils(12R,12L). A variable resistor(14b) is connected in parallel with the correction coils(2R,2L,3R,3L). A resistor(13c) is connected between a point where the correction coils(2L,3R) are connected, and a variable terminal of the variable resistor(14b). The variable resistor(14b) is adjusted to thereby allow an adjustment to the ratio between a current that flows through the first pair of correction coils(2R,2L).
