る陰極線管電子銃構体。In an electron gun assembly that is sealed in the glass neck of a cathode ray tube and is equipped with a cathode, multiple electrodes, and an insulator support rod that sequentially supports them at predetermined intervals, the anode closest to the cathode and the fluorescent surface. A discharge suppressing electrode attached to surround the insulating support rod is in contact with at least one electrode to which a voltage lower than the anode potential is applied, excluding the electrode, and the opposite insulating support rod in which the electrode support part is buried. A cathode ray tube electron gun structure characterized by locally chamfered corners.
