摘要： A cathode ray tube has a convergence regulating means 7, positioned on the periphery of a neck portion 1B, which is used for regulating the orbit of each electron beam emitted from electron guns contained in the neck portion 1B of the CRT envelope. The convergence regulating means 7 is equipped with high magnetic permeability members 18 for preventing the electron beam from being affected by terrestrial magnetism. Each of the high magnetic permeability members is spaced from the outer peripheral face of the envelope without direct contact therewith. With this arrangement the glass of the neck portion is prevented from deterioration.
