PROBLEM TO BE SOLVED: To provide a closure that allows a large number of trays to be installed in a case with high density and makes the size of the case compact.SOLUTION: Trays 8 in a case are stacked in a direction parallel to a direction A in which an upstream cable extends. Each tray 8 has a support part that supports the tray in such a manner that the tray can rotate around a tray rotation axis extending in a direction orthogonal to the direction in which the upstream cable extends. The support part is located on a tabular tray surface 82a at one side of the direction of the tray rotation axis and has an axial rod parallel to the tray surface. The axial rod rotatably engages with a rod holding part located on a frame 5. The frame 5 has rotation angle regulation parts 52a and 52b that regulate rotation of the tray 8 in such a manner that each tray surface is inclined to the direction A in which the upstream cable extends. |
