An advertisement frame is provided to combine facilities that constitute a lighting equipment inside an advertisement signboard by inserting the facilities into the frame through a rail combination, thereby improving a working efficiency. A coupling unit bends an upper protrusion(18) to have a gap with a top external protrusion(30) by bending the external protrusion(30) at right angle on a frame(2), to form a circular protrusion(20) whose portion is cut at an end. A supporting protrusion(22) is formed in parallel with the frame(2) inside the circular protrusion(20). A projection portion(14) is extended from an end of the circular protrusion(20) to be orthogonal with a frame surface, to form a space portion(32) for receiving a stabilizer on top of the projection portion(14). |
