PROBLEM TO BE SOLVED: To largely reduce labor and cost required for repairing and inspection, by easily attaching-detaching a moving door in an opening-closing door. SOLUTION: A fixed door 7 is fixedly installed, and the moving door 8 is horizontally movably installed, in a lower rail member part 6 and a box-shaped cross-sectional frame material 32 (an upper frame material) having a guide groove 38 on an under surface. The fixed door 7 and the moving door 8 are constituted by fitting a light transmissive plate 9 in an opening-closing door frame composed of an upper horizontal sash bar 16, a lower horizontal sash bar 17, a vertical sash bar 18 and a vertical sash bar 19. One side of the guide groove 38 has a hanger rail 34 for suspending a door roller 39 of a door roller support member 35 detachably arranged in an upper part of the moving door 8 by a fixing bolt 47 as a cantilever. The door roller support member 35 is provided with a floating preventive bolt 43 for preventing the door roller 39 from slipping out of the rail. The floating preventive bolt 43 is attached and detached from the door roller support member 35, and the door roller support member 35 is separated from the moving door 8 so that the door is obliquely inclined and can be extracted from a lower part of the hanger rail 34.
