ABSTRACT:
A shadow mask color picture tube comprising a frame having two first parts each extending in a same direction and two second parts each extending in a direction perpendicular to the first parts and holding the shadow mask. A stud pin is provided at each of four corners of the skirt, and a first supporting member is provided on each of four corners of the frame. The first supporting members are connected to the stud pins so as to support the frame elastically on the skirt. Non-extensible, flexible thin metal members are provided so as to pull both the first parts of the frame in the same direction with respectively equal forces to the skirt of the panel. The forces act in the direction substantially parallel to that in which the first parts of the frame extend.
