There is a storage type sliding door device 70 that can be stored therein (see, for example, Patent Document 1).

This sliding door device 70 is connected by connecting plates 75, 75 at the corners of the upper and lower ends of plate members 74, 74 arranged in parallel with a gap therebetween, and a first storage space for the second door 72 is formed inside. Similarly to the first door 71, the door 71 includes a second door 72 in which plate members 76, 76 arranged in parallel are connected by connecting plates 77, 77. The second door 72 may be composed of a single plate material.
Reference numeral 73 denotes a traveling body such as a roller attached to the connecting plates 75, 75, 77, 77, and is configured to travel in the rail 78.

  However, the sliding door device 70 having the above configuration is very weak against a vertical load on the plate surface when the plate members are connected only by the connecting plates 75 and 77, and is easily deformed by an external force, thereby hindering smooth opening and closing of the sliding door. There was a problem.

  For this reason, there is a sliding door device 50 previously proposed by the present applicant. The sliding door device 50 is a storage type sliding door device configured such that the front door can be stored in the rear door, and the receiving notch is formed on the upper surface of the rear door, and the entrance notch is formed on the upper side of the front door. The doors are arranged at positions where they do not interfere with each other.

By the way, this sliding door apparatus 50 opens one side surface of the rear door 52, and provides the notch part m for reception in the upper surface. The front door 51 is provided with notches n for entry at the top of both side surfaces, and door wheels 53 and 53 are arranged.
Then, as shown in FIG. 5, the sliding door device 50 is assembled by allowing the front door 51 to enter from the open side surface of the rear door 52 with the rear door wheel 54 b attached to the rear door 52. The entry notch n formed in the front door 51 enters the upper surface of the rear door 52 beyond the notch m and is combined with the shape shown in FIG.
Next, as shown in FIG. 5C, a U-shaped flange f having a door wheel 54a in front of the rear door 52 is attached to the front of the rear door 52 by appropriate means such as screws and bolts so as to straddle the front door 51 ( For example, see Patent Document 2).

However, since the front door is provided with the notches n for entry at the upper part on both sides, the support strength is not sufficient, and there is a problem in that the sliding door can be smoothly opened and closed.
