PURPOSE: A neck shielding device of cathode ray tube is provided to effectively prevent an inflow of foreign substance from the neck, recycle high temperature air such as a print furnace, and easily exchange a filtering net due to provide a simple structure. CONSTITUTION: The A neck shielding device of cathode ray tube includes a bracket(25) fixed to a frame(15) of a fixture, a base(26) firmly attached to the bracket(25), a U-shape sectional cover(21) fixed to an upper surface of the base(26), an elastic member(27) equipped between the U-shape sectional cover(21) and the base(26). The filtering net(24) is equipped between the elastic member(27) and the U-shape sectional cover(21) to both performs a reciprocation operation and exchange with easy between the first and second cover rings(22,23).
