Claims

[Claims for Utility Model Registration] (1) A rectangular perforated part having a large number of electron beam passage holes and formed on a spherical surface, extending around the outer periphery of the spherical perforated part, and , a non-porous part formed on a spherical surface that follows the spherical perforated part, a step part extending from the outer peripheral edge of the spherical non-porous part in a direction substantially perpendicular to the tube axis, and from the outer peripheral end of this step part. A color cathode ray comprising a shadow mask structure consisting of a shadow mask having a skirt extending substantially in the direction of the tube axis, and a mask frame to which the shadow mask is fixed by the skirt, supporting and reinforcing the shadow mask. The tube is disposed between the inner surface of the step portion of the shadow mask and the flange surface of the mask frame, and the fixed end portion is fixed to either the inner surface or the flange surface of the step portion, and A color cathode ray tube characterized by comprising a vibration damping member having a free other end and facing the other surface with elastic force. (2) The color cathode ray tube according to claim 1, wherein the fluorescent surface is of a stripe type, and the damping member is attached only to the rectangular sides of the shadow mask.
