Abstract
A deflection yoke has magentic field correcting auxiliary yokes (5) disposed at the flare side end of the insulative bobbin (2) for holding a pair of horizontal deflection coils (3) and a pair of vertical deflection coils (4), each magnetic field correcting auxiliary yokes (5) comprising a long and slender arc shaped core (6) disposed along the end portion of either of the horizontal deflection coils (4) or the vertical deflection coils (4) and a pair of auxiliary coils (8R, 8L) which are wound on the core (6) and connected in series to the vertical deflection coils (4); and thereby the raster distortion and mis-convergence are substantially reduced.
