PROBLEM TO BE SOLVED: To secure the degree of freedom of the layout of each drive means and perform maintenance easily by open-close moving an open-close wall body which open-close at an opening, and by moving a movable wall body which closes other portion of the opening by putting close to or separating far from the open-close wall body by moving the movable wall bodies to respective locations by other drive means. SOLUTION: For opening an open-close wall body 4, drive means 7, 7' is driven and moved backward so as to separate the movable wall body 5 from the open-close wall body to a position where it overlaps with the open-close position. Then, the drive means 6 is driven and the open-close wall body 4 is moved and opened to the side of an exterior wall 2. By doing this, the fully opened open-close wall body 4 is located at the outdoor side relative to the movable wall body 5 and is overlapped. Also for closing the open-close wall body 4, the drive means 6 is driven, the open-close wall body l4 is moved to one side of the opening 3 thereby closing the wall body 4, the drive means 7, 7' is driven, the movable wall body 5 is advanced and moved so as to come close to the open-close wall body 4 and comes to a butted position and is laterally arranged flush with the open-close wall body 4 fully closed in open- close direction. |
