Abstract
A net guide for a wire screen, made to absorb an impact by causing connections of many guide pieces of a net guide formed by the connections of the guide pieces to have a stretchability. A net guide going in and out from a lower end of a movable frame in compliance with an opening/closing of a net to thereby guide a lower end of the net is constituted by connecting, by a wire, many guide pieces formed approximately like a U-letter by a bottom part and a standing wall part. The wire is inserted through through-holes of the guide pieces, and the guide pieces under a connected state are pressed by a coil spring giving a tension to the wire.
