請求項２項記載の偏向ヨーク。[Claims for Utility Model Registration] (1) An auxiliary coil is wound around the center of a U-shaped magnetic core near the electron gun side opening of a deflection yoke attached to an in-line color picture tube. A pair of vertical magnetic field correctors are formed to generate a magnetic field between the tips of the legs of the sides, and the legs of the U-shaped magnetic cores of the vertical magnetic field correctors are perpendicular to the traveling direction of the electron beam in the inline array. A deflection yoke configured to cause a vertical correction magnetic field in the same direction as the vertical deflection magnetic field to be generated from the U-shaped magnetic core leg by passing a current with a vertical deflection period through the auxiliary coils of the pair of vertical magnetic field correctors, which are arranged facing each other. 2. The deflection yoke according to claim 1, wherein the tip of the leg of the U-shaped magnetic core approaches the screen surface side of the picture tube. (2) The pair of vertical magnetic field correctors are tilted in the electron beam traveling direction and arranged to face each other so that the U-shaped magnetic core leg tips of the pair of vertical magnetic field correctors approach the screen surface side of the picture tube. 2. A deflection yoke according to claim 1, characterized in that said deflection yoke is constructed as follows. (3) The U-shaped magnetic core legs are bent in a direction in which the leg tips of the U-shaped magnetic core approach the screen surface side of the picture tube. Deflection yoke as described in section.
