Open and close. FIG. 5 shows a conventional steady rest device. The steady rest roller (a) is placed in the opening (c) formed at the lower end of the hanging door (b), and the lower end portion of the hanging door (b) is shown. Is guiding you.

By the way, in the conventional steady rest roller (a), its shaft (d) is screwed into an anchor nut (e) embedded in the floor, and is fixed by the nut (f). However, in such an attachment structure, the anchor nut (e) is difficult to embed, and the anchor nut often loosens during use. Some sliding door devices have a door pocket, and when the sliding door is opened, the sliding door fits in the door bag. However, the steady rest roller of the sliding door device is attached to the inside of the door bag. Due to the relationship, its location is relatively easy. However, when the hanging door is mounted on the front surface of the frontage open frame, the positioning of the roller receiver for mounting the steady rest roller is troublesome, or the roller receiver is exposed to impair the appearance. Obtaining the position to fix the roller receiver from the position of the hanging door is poor in workability, and there are many cases in which a steadying roller cannot be attached accurately due to a positioning error.
