The invention provides a roll screen device in which a fastener element of an extremely thin fastener tape can be employed as a guide protrusion in both side edge portions of a screen which is taken up by a take-up shaft. An inner rail (23) is embedded into an inner side of fixed guide rails (20) which guide a guide protrusion (13) in both side edge portions of a screen (11) which is taken out of a take-up shaft (10). A guide groove (24) to which the guide protrusion (13) can be inserted is formed in the inner rail (23), and a pair of inward flanges (25) are provided in an opening end portion of the guide groove (24). A pair of rail members (31) which are provided with an outer side protrusion (33) and an inner side protrusion (34) having different heights in both side edge portions of a rail base plate (32) is embedded as such a combination that the higher outer side protrusions (33) are confronted, and a slit shaped micro gap (35) is formed between opposed portions of the lower inner side protrusion (34), into the guide groove (24) in such a manner that the micro gap (35) is opposed to a guide gap (26) formed between the opposed portions of the inward flanges (25), and the guide protrusion (13) is slid and guided in a come-off preventing state by the inner side protrusion (34), so that an extremely thin fastener element can be used as the guide protrusion (13).
