とを特徴とするカラーブラウン管。[Claims for Utility Model Registration] An electron gun equipped with a conical cylindrical contact structured to close the gap between the inner wall of the neck glass and the shield cup using a shape memory alloy whose shape changes with changes in temperature. In this case, the conical tube contact has a structure in which a wave-shaped ring-shaped element made of a shape memory alloy is attached to the upper part of a metal foil conical tube, so that even if the inner diameter of the neck of the cathode ray tube varies due to manufacturing tolerances, the cathode ray tube A color cathode ray tube, characterized in that the upper part of the conical cylinder contact is tightly attached to the inner wall of the inner neck without any gap.
