Abstract
The frame (30) comprises flat sides (30a, 30b, 30c, 30d) disposed along the lateral faces of a right prismatic surface. The sides (30a, 30b, 30c, 30d) of the frame (30) comprise an outer panel (31) and an inner panel (32) which are assembled and fixed to each other and are each constituted by a portion of a thin metal strip preferably reinforced by ribs. Devices (34) for suspending the frame (30) in the glass case of the cathode ray tube may be fixed by clipping or by welding on corner portions (33) of the frame (30).
