<p>PROBLEM TO BE SOLVED: To provide a protecting fence excellent in crime preventing property which can ensure screening function while having lighting property and ventilating property, and also has a sufficient strength. SOLUTION: A number of lattice members 5 formed of a plastic lattice member body 8 having a pair of blade plates 7, 7 integrally protruded on both side parts of a cylindrical support part 6 and a metal reinforcing beam 9 inserted into the cylindrical support part 6 of the lattice member body 8 in such a manner as to be non-rotatable are arranged between a pair of frame members on both sides orthogonal to the longitudinal direction of the lattice members 5 in such a manner that the tip parts of the opposed blade plates 7, 7 of the adjacent lattice members 5 form a prescribed space S in the blade plate thickness direction, and mutually superpose in the blade plate lateral direction. Both ends of the reinforcing beam 9 of each lattice member 5 is fixed to both the frame members.</p> |
