Abstract

PURPOSE:To avoid the damage of a pin by providing beforehand a cap-shaped protective plate for the glass pin which is provided for fixing a shadow mask in a shadow mask-system color cathode ray tube. CONSTITUTION:Shadow mask 4 having a number of small holes is arranged oppositely to fluorescent film 3 which is provided on the inside face of face glass 2 of a shadow mask-system color cathode ray tube. At this time, for the purpose of making fluorescent film 3 and mask 4 opposite to each other correctly, glass pin 9a is provided into one body inside glass vaccum outside surrounding vessel 1 which is united with face glass 2, and this pin and spring 10 provided in mask 4 are coupled. At this time, protective plate 11 consisting of a cap-shaped metallic thin plate having cut 12 is interposed between pin 9a and spring 10. Thus, the damage of glass pin 9a can be prevented very simply and cheaply.
