Abstract: PROBLEM TO BE SOLVED: To correct a deflection error caused by an impact to a shadow mask and a deflection error cashed by thermal expansion during use for a long time and stably display a good-quality image by making the thickness and the length of the tilt sections of the first members of holders elastically supporting a mask frame against a face panel thinner and shorter than those of the second members. SOLUTION: A shadow mask 10 is removably hooked on stud pins 14 provided inside the corner sections of the skirt section 2b of a panel 2 via the holders 12 of elastic supporters fixed outside the corner sections of a mask frame 9. Each holder 12 is constituted of the first and second members having slant sections respectively, the thickness of the first member is made thinner than the thickness of the second member, and the length of the first slant section is made shorter than the length of the second slant section. The mislanding by thermal expansion and the mislanding by external shock to the mask frame 9 can be concurrently and effectively compensated.

Abstract: PROBLEM TO BE SOLVED: To restrain any deviation of beam landing due to an outside shock and correct a color shifting due to expansion by providing means for constraining deviation of an elastic supporter against the outside shock in the elastic supporter for engaging a shadow mask. SOLUTION: A fixed portion 32 fixed to a mask frame 8 and one end of an engaging portion 34 having an engaging hole 33 engageable with a stud pin 30 are bend, respectively, thereby forming inclined portions 35a, 35b, each end of which are welded at welding points indicated by X mark, so that an elastic supporter 31 is formed into substantially V shape. In the supporter 31, a plate-like bending portion (projecting piece) 37 projects in the fixed portion 32 by bending straight toward the engaging portion, and a slit (receiving portion) 38b, into which the bending portion 37 is fitted, is formed in the engaging portion 34, respectively. When the stud pin 30 is fitted into the engaging hole 33, the bending portion 37 is inserted into the slit 38b.
