    • When three or four panel attachment springs 3 are welded to side portions of an aperture grill 1 (or 21), the aperture grill is disposed so that a grill 107 should be opposed to a predetermined reference plane. The springs are disposed by three or four spring positioning means. A posture of the aperture grill 1 (or 21) is adjusted based on measured results of the respective measurement position Z.sub.0 to Z.sub.4 of the grill 107. Positions of spring pins for supporting springs on the spring positioning means are agreed with positions of panel pins provided on a panel. Thereafter, the respective springs are simultaneously welded to the side portions of the aperture grill. Thus, it is possible to precisely weld the springs to side-portion positions of the aperture grill. When the four springs are welded, it is possible to simultaneously weld the four springs by one equipment.
