This prevents the first side plate 6 from being inadvertently rotated inward during transportation and from being dislodged from the engagement between the engagement claw 23 and the engagement hole 24 by moving upward. A clue is lost due to the rotation of the first side plate 6, and an accident of dropping the container can be prevented.

The inclined surface 29 in the concave portion 28 only needs to have an angle that cannot be used as a clue, and is not limited to a flat surface, but may be formed as a curved surface. Further, the concave portion 28 can be made shallow, or can be formed into a concave-convex shape having such a width that a finger cannot be inserted.

When the direction of the top and bottom of the container is clear, the wall surface 26 serving as a handle may be formed only on the upper side wall of the concave portion 27.
In addition, in the case of standing up a container, it can be provided in a part that may be used as a hook,
Conversely, by defining the wall surface 26 serving as a handle, it is possible to determine the direction of the top and bottom when transporting the container in a predetermined direction. When there are a plurality of recesses 27, particularly three or more recesses, the wall surface 26 having the above-described shape may be formed only in the recess 27 at a position suitable as a handle.

Further, in the above embodiment, the transport container for storing the pancake wound with the magnetic tape as the tape-shaped recording medium has been described, but it is also possible to store various disk-shaped articles having a through hole in the center. It can be easily applied, and an optimal shape can be appropriately adopted according to the size and weight of the disk.
