PROBLEM TO BE SOLVED: To resolve the problem of asymmetry caused by temperature drift of the top/bottom of a scope and provide a similar characteristic level to a 4-point support color sorting mechanism by positioning a support spring, which connects a color sorting mechanism of a color cathode-ray tube to a panel, at a fitting angle relative to the X axis and Y axis. SOLUTION: Welding points for welding support springs to a color sorting mechanism 1 are arranged toward a panel side than the Z coordinate of a metal stud in the Z axis direction of the color cathode-ray tube. The welding points W of the support springs 3B, 3C, which are connected to left/right opposed frame B members 5 extending parallel in the Y axis direction out of the support springs 3A, 3B, 3C, to spring holders 7B, 7C are shifted to the panel side to be positioned at a fitting angleθ. The support spring 3A is also treated in the same way. This constitution can optimize the correction of mislanding of an electron beam by the temperature drift and improve the characteristics without increasing the product and production costs.
