Claims

[Claims for Utility Model Registration] In an insulating molded part having a first groove and a second groove, a horizontal or vertical main deflection coil is formed into a saddle shape by winding an electric wire in the first groove. and winding an electric wire in the second groove to form an auxiliary coil having an arbitrary shape including at least two V-shaped side portions located within a window surrounded by the main deflection coil, In the deflection yoke in which the main deflection coil and the auxiliary coil are wound with continuous windings, when the yoke is attached to the picture tube neck part, the deflection yoke is located near the electron gun in the picture tube. The shape of the second groove is changed so that the two side parts of the V-shaped auxiliary coil form a Y-shape, and in the vertically straight part of the Y-shape, the electric wire is wound there and reciprocated. A deflection yoke characterized by having magnetic fluxes canceled out by each other.
