Abstract
In a deflection yoke including a horizontal deflection coil, an insulation frame, a vertical deflection coil, and a ferrite core arranged in this order outwardly, on an outer wall of a minor diameter portion of the insulation frame, a plurality of elastic projections are provided that are arranged in a standing condition to hold an outer wall of a minor diameter portion of the ferrite core. The ferrite core thus can be held in an optimum position in a vertical axis direction. Preferably, the outer wall of the minor diameter portion of the ferrite core has a tapered portion having a diameter decreasing in a direction towards an end side of the minor diameter portion that is held by the elastic projections. The ferrite core thus can be held also in an optimum position in a tube axis direction. A color cathode ray tube device with reduced YH crossed misconvergence thus can be realized.
