| Zusammenfassung: | A deflection yoke arranged on an outer part of a funnel of a cathode ray tube includes a holder for housing a ferrite member as a magnetic field correction part for varying a main magnetic field, and the ferrite member is fixed and held by inner walls as resilient members in a housing portion of the holder, thereby holding the ferrite member at the desired position with a simple construction and realizing a cathode ray tube apparatus with reduction of cost and secure convergence correction. |
