CATHODE-RAY TUBE AND METHOD FOR MANUFACTURING THEREOF, COLOR SELECTION MECHANISM, AND FRAME FOR THE COLOR SELECTION MECHANISMABSTRACT OF THE DISCLOSUREThe present invention provides a color cathode-ray tube, a method for manufacturing thereof, a color selection mechanism, and a flameframe for the color selection mechanism, in order to improve the temperature drift of the beam landing. According to the present invention, the color selection mechanism having the flameframe formed of a pair of supporting members and a pair of elasticity providing members in which a color selection mask is provided with tension between the pair of supporting members is provided. Also, as the flameframe, such as a flameframe in which the pair of elasticity providing members is made of a flat plate and a surface of the plates is opposed to each other, a flameframe in which [he pair of supporting members with approximately L-shaped cross section is inclined and disposed, or a flameframe in which both of the elasticity providing members and the supporting members are combined can be employed. The present invention provides the color cathode-ray tube including these cc for selection mechanismFigure 1
