Abstract
A color selection apparatus for a cathode ray tube. A mask frame having a pair of supporting members is disposed in parallel and spaced away from each other. A pair of elastic members is disposed between and coupled to the supporting members. A tensioned mask is coupled to the supporting members and is provided with a plurality of beam-passing apertures. A spring assembly includes a hook having a frame fixing part fixed on the mask frame and a spring fixing part and a spring fixed to the spring fixing part. The hook has a cut-away portion defined by cutting a portion of the frame fixing part. The cut-away portion forms a welding portion for welding the hook to the mask frame.
