CATHODE-RAY TUBE

PROBLEM TO BE SOLVED: To provide a cathode-ray tube which can prevent mislanding caused by thermal expansion, etc., without use of any expensive bimetal component and can reduce damage of a fixing pin in association with mounting and removal of a color selecting mechanism. SOLUTION: In this cathod-ray tube, a plate-shaped supporting member 20 for mounting a color selecting mechanism on the inside of a phosphor panel is composed of a welding part 21 to be welded to the side with color selecting mechanism, a locking part 22 to be locked to the side with phosphor panel, and an intermediate part 23 which couples the two parts 21 and 22, and a pair of folding traces 24 to partition the welding part 21, locking part 22, intermediate part 23 are provided while forming a prescribed angle θ with the direction A across the width of the member, and within the locking part 22 a second folding trace 24a is provided for correcting the inclination of the plane of the locking part 22 with respect to the plane of the welding part 21.
