The shaft pin 7 is located near the front end of the lower edge of the sleeve plate 10.
A bearing groove 10a is cut into which the sleeve plate 10 is fitted, and an inclined end surface 10 is formed near the front of the upper end of the sleeve plate 10.
b is formed, a V-shaped notch 10c into which the retaining rib 6a enters is formed in the upper part of the rear end of the sleeve plate 10, and a reinforcing rib in the depth direction is formed along the upper edge of the notch 10c. 10d is provided protrudingly.

(c) Lid plate 3 This lid plate 3 includes a cap 11 having a front flange 11a and a side flange 11b, and left and right arm plates 12 projecting downward from the rear inner surface of the same side flange 11b.
The lower surface of the rear end of the cap 11 is formed with a click groove 11c that engages with the click strip 4b, and the lower part of the arm plate 12 is formed with a click groove 11c. A bearing hole 12a that fits into the shaft pin 8 is bored, and on the outer surface of the arm plate 12 below the bearing hole 12a, there is an inclined inward cut in the shape of a fan that expands downward. A stepped surface 12b is formed.

By the way, in order to assemble the front plate 2 to the case body 1, the front plate 2 is attached to the back of the sleeve plate 10 with the bearing groove 10a of the sleeve plate 10 facing directly above and close to the shaft pin 7 of the side plate 6. If the front plate 2 is pushed forward in such a way that the edge does not touch the retaining rib 6a of the main body 1, the upper edge of the bearing groove 10a will easily fit into the shaft pin 7, and the front plate 2 will be pushed forward. The plate 2 is pivotally connected to the main body 1, and then the front plate 2 can be raised vertically.

On the other hand, in order to assemble the cover plate 3 to the case body 1,
If the lower end of the arm plate 12 is positioned directly above the shaft pin 8 of the side plate 6, and the cover plate 3 is pushed downward,
