COLOR CATHODE-RAY TUBE, COLOR SELECTION MECHANISM FOR COLOR CATHODE-RAY TUBE, AND FRAME OF COLOR SELECTION MECHANISM

摘要

PROBLEM TO BE SOLVED: To prevent distortions in a screen due to vibration of a strip body 8. SOLUTION: In a color cathode-ray tube, a radius of curvature RA of an end 21 of a support members 2, 3 for supporting an aperture grille 10 of a color selection mechanism 1 is made smaller than a radius of curvature Rz of a central portion 20 thereof. This allows a damper wiper 12 to make contact with the entire strip body, even when the strip body 8A on the end is twisted.
