Abstract

PURPOSE:To obtain a good convergence from a simple constitution of a device, by arranging a pair of magnetic units at a face-to-face position to a space between a bobbin and the inner circumferential face of upper and lower winding parts on a vertical deflection yoke at the side of small diameter from almost the center axially of the vertical deflection yoke. CONSTITUTION:A ferrite core 30, having end parts of large and small diameter in the direction of its axis, is formed by cylindrically combining the first and second ferrite cores 31, 32 that are axially divided into two sections. In intermediate portions of the first and second ferrite cores 31, 32 that are in a face-to-face relation with each other, winding parts 33, 34 are set and windings 35 are equipped. On inner faces at least at the side of small diameter of a deflecting yoke, magnetic units 36, 37 are provided.
