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. 【課題】筐体内に多数のトレイを高密度実装することができ、筐体の大きさをコンパクトにできるクロージャを提供する。【解決手段】筐体内のトレイ８が、上流側ケーブルの延びる方向Ａと平行な向きで積層され、かつ、それぞれ上流側ケーブルの延びる方向と直交する方向に延びるトレイ回転軸を中心に回転可能に支持する支持部を備え、支持部は、平板状に沿うトレイ面８２ａに対してトレイ回転軸方向の一方側に設けられ、トレイ面と平行な軸棒部を有し、軸棒部がフレーム５に設けられた軸保持部に回転可能に係合されており、フレーム５は、各トレイ面が上流側ケーブルの延びる方向Ａに対して傾斜した状態でトレイ８の回転が規制される回転角度規制部５２ａ、５２ｂを備えている。【選択図】図６
