PROBLEM TO BE SOLVED: To prevent cables for electrically connecting a sensor for a movable door to a controller for an upper frame from being loosened when the movable door is moved for opening/closing. SOLUTION: An upper frame 1 is formed by a first upper frame portion 30, a second upper frame portion 40 and a cover material 50, and a driving pulley, a driven pulley, a controller 10, etc., are mounted on the first and second upper frame portions 30, 40. A belt 7 is wound on the driving pulley and the driving pulley. A storage portion 54 is formed on the cover material 50. A sash roller provided on the movable door 11 is hung and supported on a rail of the first upper frame portion 30 and its connection fitting 14 is connected to the belt 7. A flexible wiring line 19 for connecting a sensor mounted on the movable door 11 to the controller 10 is arranged in the storage portion 54 in a long U-shape, so that the flexible wiring line 19 can be moved in order in the storage portion 54, when the movable door 11 is moved for opening/ closing, and prevented from being bitten or entangled into the driving pulley member, the driven pulley or the sash roller. |
