Metallic wires 32a of a prescribed diameter to be used as vertical wires are disposed at prescribed intervals on one opposed rail frames of the body 24 which is kept curved. The ends of the wires 32a are welded and fixed to the rail frames. Metallic wires 32b to be used as horizontal wires are disposed at prescribed intervals on such wires 32a and the ends thereof are welded and fixed to the other opposed rail frames. The crossed points of the vertical wires and horizontal wires are simultaneously welded and fixed. The force F is then released and a net body 32 is stretched and fixed. | ||||||
