ABSTRACT:
Positions of paired perforations that are provided in a shadow mask and through which a vibration suppressor is to be inserted with play are deviated from each other in a horizontal direction and in a vertical direction. Since the positions of the paired perforations are deviated from each other not only in the vertical direction but also in the horizontal direction, upon vibrations of the shadow mask, the vibration suppressor surely comes into contact with, rubs against, and separates from the periphery of both of the paired perforations. Consequently, a vibration attenuating effect by the vibration suppressor is exhibited stably, and a vibration decay time can be reduced.
