PROBLEM TO BE SOLVED: To provide a simple net support structure capable of solving such problems wherein the number of parts is large, wherein creases are formed in the net, wherein the tension of the net is weak, and wherein the state of stretch of the net is instable. SOLUTION: The net support structure 10 is configured to stretch the net 20 by energizing the net in such a way as to unfold upper ends of support frames 3a-3d outward with the elastic restitutive force of the support frames 3a-3d and horizontal frames 1a-1d by connecting the horizontal frames 1a-1d set in the horizontal direction parallel to a stretching surface of the net 20, longitudinal frames 2a-2d set in the direction crossing the stretching surface of the net 20 and the support frames 3a-3d set in the vertical direction with one another, and further by connecting the support frames 3a-3d in the outward inclined state to the horizontal frames 1a-1d.
