A saturable reactor having a wire and a secondary winding is provided, and the saturable reactor is used to differentially change the horizontal deflection current flowing through the horizontal deflection coil in a vertical deflection period, thereby correcting a convergence shift. A deflection yoke characterized in that a magnetic piece is provided on an end face of the permanent magnet. (2) In paragraph 1 of the claims for utility model registration,
A deflection yoke characterized in that the magnetic piece is a permanent magnet. The brief description of the drawing has been amended as follows. The phrase "reactor" in the first line of page 8 of the specification is corrected to "deflection yoke including a reactor."

Claims

[Claims for Utility Model Registration] (1) A pair of vertical deflection coils, a pair of horizontal deflection coils formed by connecting an upper horizontal deflection coil and a lower horizontal deflection coil in parallel, and a primary winding biased by a permanent magnet. A saturable reactor having a wire and a secondary winding is provided, and the saturable reactor is used to differentially change the horizontal deflection current flowing through the horizontal deflection coil in a vertical deflection period, thereby correcting a convergence shift. A deflection yoke characterized in that a magnetic piece is provided on an end face of the permanent magnet in the deflection coil. (2) In paragraph 1 of the claims for utility model registration,
A deflection yoke characterized in that the magnetic piece is a permanent magnet.
