PROBLEM TO BE SOLVED: To correct any beam mis-landing of outward, inward, leftward and rightward deviation while restraining the deviation amount from a design position of a deflection yoke. SOLUTION: A pair of magnet structures 10 each having a plurality of magnets 12 stuck on a peripheral surface of an annular belt 11 having flexibility are held to two pairs of spindles 13a and 13b fixed to a peripheral surface of a funnel 1 in a manner of being respectively vertically extended. The plurality of magnets 12 are continuously arranged over a nearly 1/2 range of the total circumferential length of the annular belt 11 so that the direction connecting the respective N poles and S poles matches with the circumferential direction of the annular belt 11, and the magnetic poles of the magnets 12 adjacent to each other are set reverse to each other. The pair of magnetic structures 10 are positioned on the side of a phosphor screen relative to the deflection yoke 2 in the tube axis direction and on both sides in the horizontal direction with respect to the tube axis.
