Abstract

PURPOSE:To prevent the divergence of position of a shadow mask and the exfoliation of inside-tube membrane by preventing the application of the substance to be coated on the iner surface of a panel from being applied onto the top insertion part of a pin for fitting the shadow mask of a face plate. CONSTITUTION:On the top end fitting part of a metal pin 13 for fitting the shadow mask 9 of a face plate 1, a cap 17 detachable to the pin 13 is fitted, in order to prevent the spplication of the membrane of the substance to be applied on the inner surface of a panel, and after the application of self-firing substance, the formation of membrane 18 onto the inner surface of the panel is performed. Accordingly, the formation of membrane made of such as graphite on the fitting surface of the spring piece 12 of the pin 13 is prevented, and the divergence of the position between the face plate 1 and the shadow mask 9 is prevented, and the generation of foreign materials due to the exfoliation of the membrane is prevented, and in-tube discharge of an electron gun can be prevented.
