The present invention relates to a structure of a cable tray which is installed in the ceiling and arranges wires. The present invention comprises a pair of side rails which is installed in parallel to each other at constant intervals; a plurality of width frames which crosses the pair of side rails; and a horizontal frame and a vertical frame which support the side rails. A vertical section of the horizontal frame or the vertical frame is a U-shape and forms a clinching unit by connecting a connection side of the horizontal frame and the vertical frame. The present invention is provided to require the minimal number of rivets or bolts to the horizontal frame or the vertical frame which supports a cable, thereby facilitating structural lightening and improving the appearance of the cable tray. |
