A tension mask frame assembly for a color cathode ray tube (CRT) includes a frame and a tension mask installed to apply tension to the support members, and wherein a plurality of electron beam passing holes are formed. The frame includes; a pair of first and second support members separated by a predetermined distance; first and second elastic members installed between the first and second support members, and supporting the first and second support members; and first, second, third, and fourth holder units installed on the first and second support members and the first and second elastic members, and respectively including first, second, third, and fourth holders and first, second, third, and fourth springs fixed to the first, second, third, and fourth holders. The thermal expansion coefficient of the material forming the third and fourth holders is no more than that of the material forming the first and second elastic members.
