Abstract

PURPOSE: To protect a ceramic base unit from damage and improve the reliability of a cathode-ray tube, by constructing corner parts of the ceramic base unit and its support member into such a manner that said both are not contacted to each other.
CONSTITUTION: The corner part of a ceramic base unit 1 is constructed by cutting and removing its corner edges including angular parts 1a, 1b to be contacted to inner wall faces of the corner part of a ceramic support member. In such a constitution, the corner part of the ceramic support member can support the base unit 1 not by contacting the angular parts 1a, 1b but by only touching inner side faces of the ceramic support member to the ceramic base unit 1. Accordingly, generation of broken chips and cut powders of the ceramic base unit 1 at the time of insertion engagement can be completely eliminated, thus capable of surely preventing the shadow mask from being choked.
