とするカラーブラウン管。[Claims for Utility Model Registration] A shadow mask with a mask frame attached to the periphery of the mask body, which has a large number of electron beam passing holes formed inside the panel, is arranged opposite to a fluorescent screen formed on the inside of the panel. In a color cathode ray tube in which the shadow mask is supported by a plurality of stud pins provided on the panel and a plurality of support pieces attached to the mask frame and engaged with the stud pins, the plurality of support pieces is a fixing part fixed to the mask frame, a locking part facing the fixing part and engaging with the panel pin, and a slope connecting the locking part and the fixing part and inclined with respect to the tube axis. and a twist prevention portion extending from one side of the fixing portion toward one side of the locking portion, and the mask is configured such that the twist prevention portion is rotationally symmetrical with respect to the tube axis. A color cathode ray tube characterized by being fixed to a frame.
