ABSTRACT:
A cathode ray tube includes a color selection apparatus mounted between a phosphor screen and an electron gun, and support members for supporting the color selection apparatus. Each of the support members is formed by a spring including a fixed section secured to the color selection apparatus, a locking section connected to the cathode ray tube, and a center section formed between these elements. The fixed section and the center section are separated by and bent at a first folding trace, and the center section and the locking section are separated by and bent at a second folding trace. Also, if a direction along a width of the springs is X, the first folding trace has an angle θ1with a straight line drawn on the fixed section along direction X, and the second folding trace has an angle θ2with a straight line drawn on the center section along direction X, the angle θ2is greater than the angle θ1.
