However, as shown in FIG. 9, such a hinge member partially protrudes from the edge of the plate forming the box or lid. Even if such a protrusion exists, it may not be a problem in its use, but for example, it may be used in transportation containers, etc., which are transported or stored in large numbers in close contact with each other, or are stacked in large numbers. However, such a protrusion creates a dead space in the storage area, which is inconvenient.

In order to eliminate this protrusion, for example,
Publication No. 51556 proposes ``A hinge that uses plates 1 and 1 with bearings and a connection part 2 with two bearings in parallel, and connects the plates 1 and 1 so that the connection part 2 is sandwiched between them.'' However, in this hinge, as shown in "A" in Figure 4 of the above publication, the fixing part of the hinge is attached to the outer surface of the plate part of the box, lid, etc. connected by the hinge. may be exposed. Judging from the diagram above, the fixed part of the hinge is exposed when the box is covered with a plate, and the fixed part of the hinge can be freely removed. be.

Therefore, the inventors of the present invention have conducted intensive research to develop a hinge connection structure that does not create the above-mentioned dead space and in which the fixed part of the hinge is not exposed at any time.
