Claims

[Claims for Utility Model Registration] (1) A substrate and an anode arranged on the substrate with a phosphor layer attached thereto, a control electrode having a support frame opposite to the anode, and a control electrode having a support frame body facing the anode; In a fluorescent display tube comprising a filament-shaped cathode stretched upwardly facing each other, and a container portion sealed to a substrate so as to cover the anode, control electrode, and cathode, a control electrode adjacent to the control electrode is provided. The structure includes an insertion hole formed in a support frame between the electrodes, and a reinforcing member interposed between the substrate and the container part when inserted into the insertion hole. Features a fluorescent display tube. (2) The fluorescent display tube according to claim 1, wherein at least a part of the outer wall surface of the reinforcing member is tapered toward the container portion. (3) The fluorescent display tube according to claim 1, wherein the reinforcing member is formed into a prismatic shape. (4) The fluorescent display tube according to claim 1, wherein the reinforcing member is formed in a cylindrical shape. (5) The fluorescent display tube according to claim 1, wherein the reinforcing member is formed in a conical shape.
