Provided is a roll screen device. Inner rails (23) are installed within stationary guide rails (20) for guiding guide ridges (13) provided at both side edges of a screen (11) which is pulled out from a winding shaft (10). A pair of inward-facing flanges (25) is provided at the opening edge of a guide groove (24) formed in each of the inner rails, and the guide ridges (13) can be inserted in the guide grooves (24). A pair of rail members (31) each provided with an outer ridge (33) and an inner ridge (34), the outer ridge (33) and the inner ridge (34) having different heights and being respectively provided at both side edges of a rail base plate (32), is combined in such a manner that the outer ridges (33) which have a greater height are abutted against each other and the inner ridges (34) which have a smaller height form a slit-like minute gap (35) between opposing portions of the inner ridges (34), and the combined pair of rail members (31) is installed within the guide groove in such a manner that the minute gap faces a guide gap (26) formed between opposing sections of the pair of inward-facing flanges (25). The sliding of the guide ridges are guided by the inner ridges in such a manner that the guide ridges are retained by the inner ridges. The roll screen device is adapted so that thin fastener elements can be used as the guide ridges. |
