PURPOSE:To fix the mask frame diagonal shaft and the stud pin fitting shaft of spring member with high accuracy and rigidity by securing the spring member obtained relatively simply through bending of board spring member to the diagonal section of mask frame section. CONSTITUTION:Spring member 21 is integrally formed from stainless steel of 0.4mm thick through bending where a pair of securing sections 31, 32 are extended in blade in the opposite directions from the opposite sides of planar board section 30 and bent to mask frame section 19 side. Supporting section 33 folded in the opposite direction from the folding direction of the securing sections 31, 32 is extended from upper side of the board section 30 while the tip 34 is bent in same direction thus to face the supporting hole 35 to be fitted with a stud pin 22 planted on the sidewall at respective diagonal section of panel 11 against said pin 22. The supporting section 33 is movable around the board section 30 where the angle (a) making against the tube axis 23 and the angle (b) between the beam 24 and the tube axis 23 are set such that 90 deg.>a>90 deg. -beta. |
