<；P>；PROBLEM TO BE SOLVED: To provide a rolling sheet guide structure for agricultural greenhouses, preventing the breakage of sheets due to their sliding contact with each other, or with sheets and a frame, and improving durability of sheets. <；P>；SOLUTION: This rolling sheet guide structure for an agricultural greenhouse 100 for guiding an opening and closing rolling sheet which is placed in ventilation openings 15 and 13a of the agricultural greenhouse 100 includes a frame which is set on the peripheries of the ventilation openings 15 and 13a, a greenhouse side sheet 3 which is engaged with the frame, a rolling pipe which goes along the ventilation openings 15 and 13a in the horizontal direction, and a rolling sheet whose lower end is wound around the rolling pipe. The frame has a frame material which has a dovetail opening to the outside of the agricultural greenhouse 100 and is long in the opening and closing directions of the rolling sheet, a wavy elastic wire rod which is attached to the widened groove bottom of the dovetail opening and engages the greenhouse side sheet 3, and a friction reducing material which is formed in a long length crossing the longitudinal direction of the frame, has elasticity, is pushed into and attached to the dovetail opening , projects from the frame, and contacts the rolling sheet. <；P>；COPYRIGHT: (C)2010,JPO&INPIT
