特徴とする電子銃封止装置。[Claims for Utility Model Registration] A support part for supporting a cathode ray tube body and a gas flow hole for introducing gas into the cathode ray tube body are provided in the same direction as the tube axis of the cathode ray tube supported by the support part. and an electron gun support opening at the support end surface of the stemmed electron gun, and the stemmed electron gun supported by the electron gun support and the cathode ray tube body supported by the support are relatively connected to each other. and inserting the stemmed electron gun into a fixed position in the neck from the open end of the neck of the cathode ray tube body, and heating and melting the stem of the electron gun and the opposing neck part to weld them together. In an electron gun sealing device for sealing an electron gun in the net by cutting off an open end side of the net, the electron gun support includes a supporting end surface of the electron gun support that communicates with the gas flow hole. An electron gun sealing device characterized in that a small hole is provided in a nearby outer circumferential surface and the opening is closer to the support end surface than the opening on the gas flow hole side.
