Description of the Related Art As shown in FIG. 3, a stretched color selection electrode of a conventional color cathode ray tube has a pair of opposing elastic frame sides 2 and 3 and a pair of elastic frame sides 2 and 3 connected to each other. The frame 1 including the elastic arms 4 and 5
1 has a structure in which a metal mask plate 10 provided at predetermined intervals is stretched. Further, there has been proposed a structure in which the elastic frame side and the elastic arm portion are integrally formed as a rectangular ring body, and a spring effect is provided on the opposite frame side extending in the short side direction (for example, Japanese Patent Publication No. 60-6066). .

が望ましい。[0003] Each strip 11 is always given a tension so as to cancel the thermal expansion even if the electron beam collides and the temperature rises during operation of the color cathode ray tube. To apply tension to each strip 11, a compressive force is applied from the outside of the elastic frame sides 2 and 3 of the frame 1 to compress it, and the metal mask plate 1 is kept in this state.
0 is fixed to the elastic frame sides 2 and 3, and then the compressive force is removed. At this time, the tension applied to each strip 11 must be substantially uniform. Therefore, when a compressive force is applied to the frame 1, the frame 1 is moved in the longitudinal direction of the strip 11 of the metal mask plate 10 to be stretched. It is desirable to have a uniform restoring force only in these.

The conventional color cathode ray tube of a color cathode ray tube has only four joints between the elastic frame side and the elastic arm of the frame, so the difference between the maximum M max and the minimum M min of the rotational component of the restoring force is small. large. As a result, when the metal mask plate is fixed to the frame and the compression force is removed from the frame, the metal mask plate is wrinkled due to the concentration of the force perpendicular to the longitudinal direction of the strip due to the rotational component of the restoring force from the frame. There was a point.

FIG. 1A is a perspective view of a first embodiment of a bridged color selection electrode of a color cathode ray tube according to the present invention. Elastic arms 4 and 5 connecting a pair of opposing elastic frame sides 2 and 3 are branched midway, and four joints are provided on one elastic frame side 2 or 3, that is, eight joints on both sides. In addition, 10

小さくなることがわかる。FIG. 1B is a diagram showing a distribution of a rotational component of a restoring force generated when the frame 1 is compressed. It can be seen that the difference between the maximum Mmax and the minimum Mmin of the rotational component of the restoring force is smaller than when there are four joints between the elastic frame side and the elastic arm.

Also in this embodiment, the difference between the maximum value and the minimum value of the rotational component of the restoring force is considerably smaller than the conventional case where the number of joints is four. In the above embodiment, the number of joints is six and eight.
Although the case of the portion is shown, it is obvious that a case having more joints may be provided.

In this case, the rotational component of the restoring force is reduced, and the metal mask plate is not wrinkled even if the compression force is removed by fixing the metal mask plate.
