To bring two doors into close contact with each other without overlapping each other and arrange the two door flush as shown in Figure (A) when the two doors are closed by improving slide doors used in fittings and furniture.

As shown in Figure (A), a hanging rail 9 having two T-shaped branches 9b provided in the central part and curve sections 9c provided on both ends, and the two doors are each provided with a runner A10 and a runner 11B. As shown in Figure (B), a manual operation force represented by Arrow p is applied on the door L12 to pull the runner A10 out of the T-shaped branch to put the runner on a linear section 9a of the hanging rail as shown in Figure (C). Further, a manual operation force in the direction of Arrow r is applied to open the door. The door can be closed to the state as shown in Figure (A) by making operation in the sequence of reversing the above operation.
