PROBLEM TO BE SOLVED: To uniformly dry and to make a drying net light in weight, rough and no deformation by holding a square net at a small gap in a reinforcing frame of a similar shape to be engaged and fixing a square outer frame to the reinforcing frame with a coupling piece. SOLUTION: Lateral and longitudinal reinforcing levers 2, 3 are fixed in a rectangular outer frame 1 to a lattice-like net frame 10, a net 4 is extended under tension in the frame 10 to form a square net plate 5. The plate 5 is engaged at a small gap S in a reinforcing frame 6 of a similar shape. The both are fixedly welded with a coupling piece 7 to constitute a drying net 8. Thus, since respective parallel fixed parts of the frames 1 and the levers 2, 3 are formed like a truss to be scarcely deformed, there is no fear of a deformation in the case of not only during handling but also placing in a truck or a drying chamber.
