Is being done. The lid that can be attached to this container has a hinge mechanism attached to one side and a lock mechanism on the other side so that the lid can be opened only on one side. In the case of opening, operations such as opening and closing of the lid by the user and putting in and out of articles are restricted to either the left or right side of the traveling direction of the carriage, that is, the lock mechanism side of the lid, and accordingly the layout of the rails is also restricted. become.

Therefore, a pair of sliding shafts are arranged on the opposite sides of the lid so as to be aligned, and a spring for pressing the sliding shafts outward is provided on each pair of sliding shafts. The outer end of the sliding shaft can be inserted into and removed from the hole of the receiving plate that faces the outer end of the moving shaft, and each pair of sliding shafts forms the rotating shaft when the lid is opened and closed, and by engaging with the receiving plate. The applicant of the present invention has proposed a structure in which the lid can be opened by forming a locking mechanism (Japanese Utility Model Laid-Open No. 3-3594). By using this lid mechanism, it is possible to eliminate the constraint on the operating direction of the container lid and the constraint on the rail layout due to it.However, if the sliding shaft is to be removed from the hole of the backing plate to open the lid, Two sliding shafts forming a pair must be moved in opposite directions. Therefore, considerable operation force is required. Further, when the lid is automatically opened and closed in order to promote the automation of the transfer facility, the lid mechanism as described above is inevitably complicated.
