The present invention relates to a cable tray with an improved assembly structure. The present invention provides the cable tray with the improved assembly structure which includes: a pair of side rails which are arranged to face each other; a coupling hole which passes through the pair of the side rails; a transverse connection member which is arranged between the side rails to be adjacent to the coupling holes; a pair of insert units which have each screw hole connected to the coupling hole and is in contact with the side rail by being combined with both sides of the transverse connection member; and a pair of coupling bolts which combine the transverse connection member to the side rails by being coupled to the coupling hole and the screw hole outside the side rail. |
