Abstract

A color selection apparatus for a cathode ray tube includes a tension mask including a plurality of electron beam passage apertures; and a frame including a pair of support members provided along opposite sides of the tension mask and applying a tensile force to the mask, and a pair of elastic members extending from one support member to the other at ends of the same, the elastic members maintaining a predetermined distance between the support members. Each of the elastic members is hollow and includes a base that is substantially parallel to the tension mask, with extensions formed substantially perpendicular to the base at both ends thereof, and bending portions integrally formed between the base and the extensions. Reinforcing elements are formed in proximity to the bending portions to increase the strength of the elastic members in the area of the bending portions.
