Abstract:
A net body using helical wire members, comprising:a large number of transverse helical wire members formed of first helical wire members obtained by helically winding, in a predetermined lead and predetermined pitch, helical wire materials having a predetermined outer diameter in such a fashion that a diameter of a helix is about twice the outer diameter of said wire materials, crests and troughs of said wire materials have substantially a similar shape and each of said troughs is positioned outside the center of the helix, said transverse helical wires being arranged with predetermined gaps; and longitudinal helical wire members formed of second helical wire members having a different winding direction from that of said first helical wire members, and combined with said transverse helical wire members in such a fashion that respective crests and troughs engage with one another so as to permit deformation of said net body.
