A cable tray is provided to effectively support a heavy-weight cable bundle by improving a coupling structure of a side rail and a horizontal bar. A cable tray(100) includes a pair of side rails(110) and a plurality of horizontal bars(130). A plurality of slots(120) is formed in an inner surface of each side rail with a fixed interval. The slots are formed into a pocket shape having an opened top part and a closed bottom part. An elongated hole(124) is formed in a floor center of the slot. The horizontal bar includes an insertion piece(132) and a wing part(133). The insertion piece is inserted in the slot of the side rail. The wing part is formed in both sides of the insertion piece. A supporting part(132a) is formed in a central bottom end of the insertion piece. The supporting part is supported on a bottom bent end of the side rail. |
