PROBLEM TO BE SOLVED: To provide a structure for stretching a bird net solving problems that all the various equipment materials used for preventing invasion of birds on a verandah, or the like, of an apartment house have insufficient effects thereof and the building body should be damaged such as application of drilling to a wall surface in the case of the installation of the bird net to produce a strong feeling of occlusion in a tenant because the verandah is closed and the installation of a metal pipe, a rail, or the like, in a site at a higher level than that of a handrail of the verandah should be avoided from aspects of preventing a falling accident of an article. SOLUTION: The structure for stretching the bird net is obtained as follows. A plurality of stretchable and fixable supports are installed between the ceiling and the floor at both ends of outer openings of the verandah and a hoist in which a wire is assembled is mounted on one of the supports so as to stretch the wire made of stainless steel. Each ring for fixing the wire is provided in the other support. The wire is stretched between the supports, respectively, to simultaneously hang the bird net and freely perform the stretching and opening and closing of the bird net. COPYRIGHT: (C)2004,JPO&NCIPI
