さえ手段11が外れることはない。The inner frame 3 is formed by using the pressing means 11 as described above.
The plate 10 is pressed against the plate 7 side of the inner frame 3 at two positions on each side of the set to attach the plate 10 to the inner frame 3. A procedure for pressing the plate-like body 10 will be described. First, at a predetermined position of the inner frame 3, the upper end 12 of the plate 13 of the holding means 11 is engaged with the flange 9 of the inner frame 3. At this time, the other end bent portion 16 of the support member 17 is directed to the left side from the one end bent portion 15 as shown in FIG. 3, and the other end bent portion 15 is inclined at an inclination angle of about 15 °. The tip of the end bent portion 16 is separated from the upper surface of the plate-shaped body 10. In this state, by rotating the support member 17 rightward about the one-end bent portion 15, the tip of the other-end bent portion 16 comes into contact with the upper surface of the plate-like body 10 while gradually lowering. The rotation of the support member 17 is stopped in a state where the plate-like body 10 is strongly pressed with the tip of the support member 17. As the height of the distal end of the other end bent portion 16 gradually decreases and presses the plate-shaped body 10, the plate 13 rotates around its center as viewed from the front. That is, as shown by the two-dot chain line in FIG. 4, the support member 17 is rotated to the right starting from the state where the other end bent portion 16 of the support member 17 is to the left. Is large, the support member 17 is slightly rotated, and the plate-shaped member 1 is bent at the position between the two-dot chain line position in FIG.
0 can be pressed, at which time the plate 13 tilts to the right as shown by the two-dot chain line in FIG. 4, and the upper left end of the plate 13 is strongly engaged with the flange portion 9 of the inner frame 3 from below. At the same time, the lower right end of the plate 13 is
Is strongly engaged from above, so that the pressing member 11 does not come off from the inner frame 3. Further, when the thickness of the plate body 10 is slightly reduced and the plate body 10 is pressed by the front end of the other end bent portion 16 at the front position of the plate body 13, the plate body 13 is lifted upward without tilting. The upper right and left ends of the plate 13 strongly engage the flange 9 of the inner frame 3 from below. Further, the thickness of the plate-shaped body 10 is further reduced, and as shown by the solid line in FIG. Is pressed, the plate 13 tilts to the left as shown by the solid line in FIG.
And the lower left end of the plate 13 is strongly engaged with the plate portion 8 of the inner frame 3 from above, and the upper right end of the inner frame 3 is strongly engaged with the flange portion 9 of the inner frame 3 from below. The holding means 11 does not come off the frame 3.

It is necessary that the plate-like body 10 is of a size that does not easily come off. The inner frame 3 to which the plate-like body 10 is attached in this manner can be freely opened and closed by the engagement piece 5 being rotatably engaged with the engaging portion 4 as described above, and the inner frame 3 is closed. In this case, the side edges of the outer frame 1 and the inner frame 3 opposite to the one side may be locked by locking means (not shown).

0 may not be present. In the embodiment shown in the drawings, projecting pieces 21 projecting downward are formed on both sides of the lower end of the plate 13 of the holding means 11, but the projecting pieces 21 may be omitted. Further, the outer frame 1 and the inner frame 3 have a square planar shape, but may have a rectangular planar shape.
