。 An auxiliary coil is wound around the center side of the U-shaped magnetic core near the electron gun side opening of the deflection yoke attached to the in-line color picture tube.
A pair of vertical magnetic field correctors formed to generate a magnetic field between the tips of the sides are arranged in-line with respect to the electron beam. In a deflection yoke configured to cause a current with a vertical deflection period to flow through the auxiliary coils of the pair of vertical magnetic field correctors to generate a pink tension type vertical correction magnetic field in the same direction as the vertical deflection magnetic field, the pair of vertical magnetic field A deflection yoke characterized in that a magnetic piece is slidably disposed in contact with or very close to one side of a leg of at least one U-shaped magnetic core of a corrector.
