A cable tray is provided not to be deformed in spite of high load by being firmly assembled without a bolt and a nut and prevent a safety accident by not being easily disassembled. A cable tray includes a pair of rails(10), a rung(20), and a coupling unit(30). The rung is installed between the pair of rails. The coupling unit couples the ring and the pair of rails. Each of the pair of rails has an insertion space composed of supporting pieces(13) to support both sides of the coupling unit and a holding piece to hold a lower part of the coupling unit. The rung has a receiving unit composed of an upper surface, both side surfaces, and a bending unit. The coupling unit has an insertion unit inserted into the receiving unit of the rung and a flange inserted into the insertion space of the rail. |
