Claims

[Scope of utility model registration request]

(1) A rectangular door flannel having a fluorescent surface on which phosphor layers of three colors are regularly deposited on the inner surface, a shadow mask disposed at a predetermined interval on the fluorescent surface; A mask frame that supports the skirt portion of the shadow mask, one end of which is fixed to the mask frame via a bimetal, and an opening that engages with a panel pin embedded in the inner surface of the side wall of the panel near the other end. The bimetal is attached to the mask frame so as to be approximately perpendicular to the tube axis, and the direction of deformation of the bimetal is A color picture tube characterized by being arranged almost along the tube axis.

(2) The color picture tube according to claim 1, wherein the bimetal is fixed to a side of the mask frame that is substantially perpendicular to the tube axis.

(3) Utility model registration claim 1, characterized in that the bimetal, the spring, and the spring member are fixed by bending one of the ends of the bimetal and the spring member at a substantially right angle. Or a color picture tube according to item 2.
