Abstract

PURPOSE:To make an irregular strain so as not to be produced in a joint part of a shield cup by joining and fixing a field control element solidly to a top face of the shield cup, not resting on a welding device. CONSTITUTION:Each of through holes 14a-14c is installed in the specified position where field control elements 15a-15c on a top face of a shield cup 13 are installed in advance, and these field control elements 15a-15c are joined and fixed to these through holes 14a-14c by means of a method of press-in or shrinkage fit or the like. With this constitution, since these field control elements are formed almost solidly with the shield cup in substance, such joining ununiformity and complex strain as produced by a welding device are in no case produced in the shield cup utterly, so that any deterioration in a focus characteristic inherent in an electron gun is brought to nothing, and image quality of a color picture tube is improved, especially its practical effect is large enough for a high definition display.
