Abstract
A colour picture tube in which a shadow mask is attached to a frame which consists of two short sides and two long sides connected with angular elements. The ends of the short sides of the frame are connected to the angular elements in a way to leave the sides of the frame extending free from the angular elements. The skirt of the shadow mask bears against this free portion. As a result, the shadow mask 10 is less sensitive to vibrations.
