PURPOSE: Stair assembly structure of a truck is provided to shorten the assembling time of a set of stairs and to simply disassemble the set of stairs by connecting the stair assembly to a cargo compartment. CONSTITUTION: Stair assembly structure of a truck includes: a guide hole(101) having specific depth and width on the bottom of a cargo compartment(111); a movable unit(102) mounted in the guide hole to slide horizontally, having a specific space therein; a horizontal moving unit for moving the movable unit horizontally; an entrance member(103) connected to an end of the movable unit, having specific size for moving into the movable unit from an end of the movable unit; a stair assembly(104) having plural stairs, connected to an end of the entrance member; a rotating unit for rotating the assembly at the end of the entrance member; and a setting/folding unit for setting or folding the assembly with the rotating member of the assembly. When a worker pushes the assembly with a grip, the entrance member is inserted into the movable unit. Then a transfer roller(105) slides along the guide hole to move the movable unit to the other end of the guide hole. The worker keeps the assembly locked by rotating a locking unit. Therefore, the assembly is not separated from the guide hole.
