Ablenkjoch und Farbkathodenstrahlröhre

In a deflection yoke including a horizontal deflection coil 1, an insulation frame 20, a vertical deflection coil 3, and a ferrite core 4 arranged in this order outwardly, on an outer wall 20a of a minor diameter portion of the insulation frame 20, a plurality of elastic projections 21a and 21b are provided that are arranged in a standing condition to hold an outer wall 4a of a minor diameter portion of the ferrite core 4. The ferrite core 4 thus can be held in an optimum position in a vertical axis Y direction. Preferably, the outer wall 4a of a minor diameter portion of the ferrite core 4 has a tapered portion 4e having a diameter decreasing in a direction towards an end side of the minor diameter portion that is held by the elastic projections 21a and 21b. The ferrite core thus can be held also in an optimum position in a tube axis Z direction. A color cathode ray tube device with reduced YH crossed misconvergence thus can be realized.
