PROBLEM TO BE SOLVED: To enhance burglarproof performance by inhibiting an illegal intrusion through a gap between an opening/closing body means and a guide rail means. SOLUTION: The guide rail means, an inner rail means and the like are moldings made by extruding an aluminum alloy or the like. Therefore, an opened groove section can be deformed illegally by a bar or the like. A rail reinforcing means is provided inside the guide rail means to provide an outer rail and the inner rail with a structure which is hard to deform. Thus, illegal formation of a gap is prevented to inhibit an illegal intrusion through the gap. COPYRIGHT: (C)2007,JPO&INPIT
