A vibration damping member penetrates through two mounting apertures provided in a shadow mask with tension applied thereto, so as to be attached to the shadow mask in a freely movable state. The vibration damping member has two penetrating portions each passing loosely through one of the two mounting apertures and a bridge portion linking these portions. A protrusion protruding toward the shadow mask is provided in the bridge portion of the vibration damping member. This configuration regulates a tilted angle of the vibration damping member with respect to the face of the shadow mask, thus preventing a phenomenon in which a bending portion is caught by the edge of the mounting aperture so that the vibration damping member is pinned by the shadow mask. As a result, the freely movable state of the vibration damping member can be kept always, and therefore vibrations of the shadow mask can be dampened effectively and a color cathode ray tube with reduced color displacement can be provided. |
