When all the openings are to be opened, the partitioning door bodies a are sequentially moved to the end portions of the rails 5 ', 6', so that the upper runner body 1 on the hanging side and the hanging side on the hanging side. The lower runner body 3 is engaged and held by the catch 9, and the runner shafts 1a and 3a of the respective runner bodies 1 and 3 are rotatably held in the state of being engaged and held by the catch 9 in this manner. In this state, the operating member 40 is operated to operate the upper runner 2 on the door side and the lower runner 4.
Is moved up or down to remove it from each of the rails 5 ', 6', whereby the partitioning door body a can be horizontally rotated about the hanging side as a fulcrum. The openings a between the upper and lower rails 5 ′ and 6 ′ can be fully opened by sequentially arranging “a” along the wall surface.
