Avibration damping member 10 penetrates through two mounting apertures 11 provided in a shadow mask 5 with tension applied thereto, so as to be attached to the shadow mask 5 in a freely movable state. The vibration damping member 10 has two penetrating portions 13b each passing loosely through one of the two mounting apertures 13b and a bridge portion 13a linking these portions. A protrusion 14 protruding toward the shadow mask 5 is provided in the bridge portion 13a of the vibration damping member 10. This configuration regulates a tilted angle of the vibration damping member 10 with respect to the face of the shadow mask 5, thus preventing a phenomenon in which a bending portion 12a, 12b is caught by the edge of the mounting aperture 11 so that the vibration damping member 10 is pinned by the shadow mask 5. As a result, the freely movable state of the vibration damping member 10 can be kept always, and therefore vibrations of the shadow mask 5 can be dampened effectively and a color cathode ray tube with reduced color displacement can be provided. |
