ク。 An auxiliary coil is wound around the center of the U-shaped magnetic core near the electron gun side opening of the deflection yoke attached to the in-line color picture tube to generate a magnetic field between the tips of the legs on two sides. A pair of vertical magnetic field correctors formed in this manner are arranged opposite to each other so that the legs of the U-shaped magnetic cores of the vertical magnetic field correctors are orthogonal to the in-line arrayed electron beam, and In the deflection yoke configured to cause a current having a vertical deflection period to flow through the auxiliary coil and to generate a pincushion type vertical correction magnetic field in the same direction as the vertical deflection magnetic field from the U-shaped magnetic core legs, at least one of the pair of vertical magnetic field correctors A magnetic material piece is arranged approximately parallel to or in contact with the U-shaped surface of one U-shaped magnetic core and at a predetermined position approximately perpendicular to the in-line array of electron beams. deflection yoke.
