Therefore, for example, when the steadying device R of the present invention is applied to a suspension door structure with one hanging door, the steadying main body 30 is on the floor surface F under the trajectory on which the hanging door runs when closed. Thus, one end of the engagement piece 35 is installed at the steady stop position Z before the fully closed position where the lateral shake occurs, with the distal end of the engagement piece 35 facing the door in the closing direction. On the other hand, the magnet catch 40 is fitted in the closing direction door end side groove end portions 14a and 15a of the guide grooves 14 and 15 of the suspension door, and when the magnet catch 40 reaches the steady stop position Z that causes lateral vibration when closed, The engaging piece 35 is attracted and rotated by M and is configured to be magnetically held in a vertically raised state.

  Furthermore, in the above illustrated embodiment, the magnet M is composed of the first magnet m1, the second magnet m2, and the third magnet m3 · m3. However, in the steady rest device of the present invention, As long as the anti-sway position that causes the shake is reached, the number of magnets M may be one or more as long as the engaging piece is attracted and rotated to be magnetically held in a vertically raised state. For example, when the magnet M is configured by using three magnets, a magnet that magnetizes and magnetically attaches the engagement piece 35 is disposed on the door end side, and the magnetized engagement piece 35 is sandwiched therebetween. And a pair of magnets that are magnetically held from both sides are arranged on the door bottom side and installed in the magnet catch 40.
