Abstract

PURPOSE:To prevent the mislanding of electron beam by specifying the relation of the center or the supporting point of shadow mask thereby preventing the rotation of shadow mask. CONSTITUTION:One end of resilient member 49 is provided through a bimetal 50 in the proximity of four corners of mask frame, where the angle theta formed by line OC which passes through the center O of shadow mask and fixed point C and line CD which passes through the fixed point C of said bimetal 50 and the resilient member 49 and the cross point between the center of panel pin 48 and the face including the opening of the resilient member 49 or the supporting point D is approximately 90 deg. or crosses perpendicularly.
