摘要： A deflection yoke which can simultaneously achieve suppression of induction current arising from an influence of a raster rotation correction coil and correction of misconvergence which varies the current balance of horizontal deflection coils. The deflection yoke of the present invention includes a raster rotation coil, and a pair of coils sharing a single core and respectively connected in series to an upper side horizontal deflection coil and a lower side horizontal deflection coil. The pair of coils are connected such that the polarities thereof may be opposite to each other. The pair of coils suppress current induced by a magnetic field of the raster rotation coil. In order to apply a bias to the pair of coils which share the core, a single bias coil is wound on the shared core on which the pair of coils are wound. Part of horizontal deflection current is supplied to the bias coil thereby to produce a difference in current flowing through the upper side horizontal deflection coil and the lower side horizontal deflection coil. Correction of misconvergence is allowed thereby.
