SUPPORT FRAME BODY STRUCTURE, MANUFACTURING METHOD OF COLOR SELECTION BODY STRUCTURE, CATHODE-RAY TUBE

摘要

PROBLEM TO BE SOLVED: To provide a lightweight color selection body structure with a stable quality. SOLUTION: Horizontal support bodies 12a and 12b for supporting a color selection electrode 20 along a horizontal direction H is supported by vertical supporting bodies 11a and 11b extending in a vertical direction V. Positioning holes 11p and 11q are respectively arranged to the vertical supporting bodies 11a and 11b in the horizontal direction H. Positioning pins 34 and 36 are respectively fit into the positioning holes 11p and 11q. The positioning of a support frame body structure 202 in the horizontal direction H and the vertical direction V is performed by moving the positioning pins 34 and 36 in the horizontal direction H.
