The voltage supply terminal is fixed by sandwiching the joint side of the funnel (32) with the claws (41) and (42) and the voltage introduction terminal (43). The claws (41) and (42) are funnel (3
Since the surface slides while being pressed against the inner wall of 2), the conductive film (34) formed on the inner wall of the funnel (32) is damaged and scraped. The scraped powdery carbon scatters in the funnel, and when it adheres to the fluorescent film, the fluorescence becomes non-uniform, and when it adheres to the electron gun, unnecessary electrons are generated, and defects such as sparks between electrodes and other places occur. Cause Further, the voltage supply terminal is fixed to the upper end of the funnel (32) as can be seen from FIG.

In a small cathode ray tube in which a funnel and a face plate are joined by a joining material to form an envelope, and a voltage supply terminal is provided at the joint, a conductive film is formed on the inner wall surface of the funnel, and the voltage supply terminal is formed. A claw portion for sandwiching the funnel side wall to position the voltage supply terminal is formed, and a claw portion of the claw portion that abuts the inner wall of the funnel abuts a recess formed in the inner wall of the funnel on the joint side. Deploy. Although no conductive film is formed in the recess,
Even if they are adhered by coating, the conductive film should not be formed at least in the portions where the claw portions come into contact.

In FIG. 1, (1) is a funnel, and recesses (1a) and (1b) are formed in the inner wall of the upper end (joint side). The concave portions respectively have a claw portion (41) of the voltage supply terminal,
(42) is engaged. (Bonding material is omitted to make the engagement easier to see.) In the figure, the recesses and claws do not move in the horizontal direction in the figure, but the voltage supply terminal position is allowed. The recess may be elongated as long as possible. The funnel (1) is glass, and since plate-shaped glass is heated and softened to form a funnel shape with a mold, if a convex part for forming a concave part is formed on the male mold, the concave part can be easily formed. Can be formed. Conductive film (3
