Cathode ray tube having support member for color selection apparatus

A cathode ray tube including a color selection apparatus mounted between a phosphor screen and an electron gun installed within a vacuum tube assembly of the cathode ray tube, and one or more support members for supporting the color selection apparatus in the vacuum tube assembly, each of the one or more support members being formed by a spring comprising:

• a fixed section secured to the color selection apparatus;
• a locking section connected to the vacuum tube assembly;
• and
• a center section formed between the fixed section and the locking section,
• wherein 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,
• wherein if a direction along a width of the spring is X, a direction along a length of the springs is Y, the first folding trace has an angle θ1 with a straight line drawn on the fixed section along direction X, and the second folding trace has an angle θ2 with a straight line drawn on the center section along direction X, the angle θ2 is greater than the angle θ1,
• wherein a connecting hole is formed in the locking section, and the connecting hole is secured to a stud pin mounted to an inner surface of the panel of the vacuum tube assembly, and
• wherein the connecting hole is circular, and a distance of a straight line that passes through a center of the connecting hole and is perpendicular to the second folding trace is 5 mm or greater in length.
