The slide device 2 includes an outer member 22 having a substantially C-shaped cross section, which is fitted to a reinforcing frame 20 having a substantially the same length as the fixed frame 3.
The inner member 24 is slidably fitted through a ball and a ball retainer.

Further, a hanging metal fitting 21 is fixed to the inner member 24 so as to correspond to the hanging seats 14 of the hanging door 1.

The fixed frame 3 is a holding frame 33 that holds the slide device 2.
.. and a fixing holder 31 fixed to the wall surface, and a connecting and holding portion 34 for holding the fixing frame 3 in a horizontal state with bolts or the like.

The automatic closing device 5 is hung around a pulley 51 rotatably attached to a pulley attachment seat (not shown) attached to the opening-side upper end of the hanging door 1 with screws or the like. The wire 52, the wire fixing seat 53 attached to the fixing frame 3 that fixes one end of the wire 52, and the wire fixing seat 53 attached to the other end of the wire 52, move up and down in the hanging door 1 as the hanging door 1 moves. It consists of weight 54.

As shown in FIG. 1 and FIG. 2, the open posture maintaining device 6 includes a holding frame 7 adhered to the surface of the hanging door 1 by a double-sided adhesive tape or the like, and a holding frame 7 and the surface of the hanging door 1. It is composed of a sliding plate 9 which is slidably held up and down and a magnet 97.

The holding frame 7 is formed of a holding portion 71 having a substantially U-shaped cross section and mounting portions 72, 72 which are continuously provided so as to project outward from an end portion of the holding portion 71. The back surface of the mounting portions 72, 72 has a double-sided adhesive tape. And is adhered to the upper end of the surface on the side of the rammer 8 at the closed end of the hanging door 1.

The sliding plate 9 is a sliding portion having a width slightly smaller than that of the holding portion 71 of the holding frame 7.
91, an operating portion 92 that is continuously connected to the lower end of the sliding portion 91 so as to project outward, and a suction portion that has a larger width dimension than the sliding portion 91 that is continuously provided at the upper end of the sliding portion 91 and projects outwardly. The magnet 97 is bonded to the upper surface of the attracting portion 93.

In the case of the embodiment, a magnet rubber is used as the magnet 97.

Then, sliding sliding members 94, 94 made of a synthetic resin material having a U-shaped cross section are attached in the longitudinal direction of the left and right end portions of the sliding portion 91 to make the sliding of the sliding plate 9 smooth.

Since the suction portion 93 is formed so as to project outward from the holding portion 71 of the holding frame 7, when the sliding plate 9 slides downward, it comes into contact with the upper surface of the holding portion 71 and the sliding plate 9 It functions as a stopper that prevents the holding frame 7 from falling out.
