０．３０mm）を前提にした値である。When mounting the damper wire 10, the damper wire 10 is fixed while applying a compressive force to the strip-shaped end portion 13A from the direction indicated by the arrow. Then, the grid structure 3A is restored to the original shape by releasing the force after the fixing is completed, and the damper wire 10 is stretched in a tensioned state. As described above, since the damper wire 10 is kept in a tense state, a force that pulls toward the center of the grid structure 3A by the tension of the damper wire 10 is applied to the strip-shaped end portion 13A. In order to prevent the deformation of the strip-shaped end portion 13A due to the tension of the damper wire 10, it is necessary to make the lateral width of the strip-shaped end portion 13A at least 40 times the lateral width of the metal strip 1. However, the required lateral width of the strip-shaped end portion 13A varies depending on the thickness of the grid structure 3A, and a value of at least 40 times the lateral width of the metal strip 1 is the thickness of a general grid structure that has been put into practical use (0. 15mm ~
This value is based on the assumption of 0.30 mm).

There is no need for the existing spring material 9, and the damper wire 1
Since the complicated work of fixing the end portion of 0 is unnecessary, the manufacturing cost can be reduced. Further, since the welding of the welding member 14 for fixing the damper wire 10 is performed on the substantially flat strip-shaped end portion 13A, it becomes possible to adopt roll spot welding using roller electrodes, seam welding, or the like. Therefore, the welding work is facilitated and the work efficiency of attaching the damper wire 10 can be improved.

FIG. 3 is a partial perspective view showing the configuration of the color selection electrode 200. In FIG. 3, the color selection electrode 200 includes a grid structure 3B and a frame 4 on which the grid structure 3B is placed and welded.

い。The grid structure 3B has the metal strips 1 arranged at a predetermined pitch and having substantially the same width, and the slits 2 formed between the metal strips 1 for transmitting the electron beam. The same as the grid structure 3 of the conventional color selection electrode 90, but with the slits 2 located at both ends of the slit array.
The strip-shaped end portion 13B formed on the outer side of the contour has an uneven wavy shape instead of a straight line, and its lateral width is not uniform.

よる振動抑制の効果が低減することになる。Generally, the vibration condition (natural frequency, vibration mode) of a system in which both ends are fixed, such as the metal strip 1, is determined by the mass per unit length and the tension. Therefore, when the lateral width of the strip-shaped end portion is uniform, that is, when the strip-shaped end portion 13A shown in FIG. 1 is used, the vibration state of the strip-shaped end portion 13A becomes the same as that of the metal strip 1, and the damper wire 10 is used. The effect of suppressing vibration is reduced.

効果が低減することが防止される。Therefore, as in the color selection electrode 200 shown in FIG. 3, the strip-shaped end portion 13B has a contoured wavy shape so that the vibration state is different between the strip-shaped end portion 13B and the metal strip 1. Therefore, it is possible to prevent the effect of suppressing the vibration of the metal strip 1 from being reduced.

帯状端部１３Ｂのような波打形状になるとは限らない。The relationship between the lateral width and the longitudinal position of the strip-shaped end portion, that is, the contour shape of the strip-shaped end portion is determined by trial and error depending on the vibration condition. Therefore, the contour shape of the strip-shaped end portion is defined as that of the strip-shaped end portion 13B. It does not always have such a wavy shape.

Is prevented from being reduced.

Similar to the grid structure 3 of the conventional color selection electrode 90, the strip-shaped ends 13C formed outside the slits 2 located at both ends of the slit array have a lateral width of at least 40 times the lateral width of the metal strip 1. This is similar to the grid structure 3A of the color selection electrode 100 of the first embodiment described with reference to FIG. 1, but the structure for attaching the damper wire 10 at the strip-shaped end 13C is different. That is, both ends of the damper wire 10 are pressure-bonded and fixed to the upper surface of the strip-shaped end 13C of the grid structure 3C by using the pressure-bonding member 15.

If the tension of the tongue piece 17 is weak, the tension can be strengthened by making the inclination angle of the mountain bent portion 18 of the tongue piece 17 steep or widening the angle of the valley bent portion 19. On the other hand, when the tension of the damper wire 10 is strong, the tension can be weakened by loosening the inclination angle of the mountain fold portion 18 or narrowing the angle of the valley fold portion 19.
