Abstract
A shadow mask support frame for a color cathode ray tube has a rectangular shape overall comprises two end uprights and two lateral uprights. The lateral uprights have a straight main part and two end parts each connected by at least one joining portion to an end upright. The lateral uprights have axes parallel to each other situated in a plane parallel to a reference plane of the frame. Each of the joining portions is in contact through a lateral face with an internal face of a substantially flat wall perpendicular to the reference plane of the frame, so that the end uprights of the frame are in abutment on the joining portions.
