Support members for the mask frame of a CRT

摘要

In a color cathode ray tube, a shadow mask is supported by a mask frame and is so arranged in a panel section of an envelope as to face a phosphor screen formed on an inner surface of a face plate of the panel section. The mask frame has four flat corner sections which are arranged substantially parallel to an axis of the envelope, and is coupled to a skirt section of the panel section through a stud pin by support members which are fixed to the flat corner sections, respectively. Each of the support members has a resiliently deformable structure which is provided with a straight deformable plate section and first and second plate sections extending from both ends of the straight deformable plate section. The first section is fixed to the flat corner section and the second section is coupled to the stud pin.
