PROBLEM TO BE SOLVED: To provide a deflection coil enabled to correct a middle part vertical misconvergence with relatively simple structure at a low cost. SOLUTION: A vertical subdeflection coil 2, having the same functions as those of a vertical deflection coil, mounted to a neck part of a receiving tube 3-2 on the back side of a deflection coil body 1, and a circuit restricting the current flowing into the vertical subdeflection coil, when the current flowing into the vertical deflection coil main body 1 exceeds a prescribed value, are installed. |
