The hanging door 8 is hung on the front side of the frontage of the partition, and the frontage Open and close. Traveling tool attached to the upper end of the hanging door 8 (not shown)
Runs on the upper rail above the frontage, and the steady rest roller 7 standing vertically from the roller receiver A is housed in the lower end opening 9 of the hanging door 8. A screw is formed on the shaft 10 of the steady rest roller 7, which is screwed into the screw hole 1 shown in FIG. 1 to stand up, and is further tightened by a nut 11. The tightened nut 11 serves as a vertical guide for the shaft 10 and also fixes the shaft 10. Especially, the brim 3 formed by burring forms the R surface at the boundary with the upper surface 2 as shown in FIG. 1 (b). Although it has 18, the R surface 18 is compressed by fastening the nut 11, and as a result, the shaft 10 screwed into the screw hole 1 is fastened.

FIG. 3 is a transverse cross-sectional view in which the hanging door 8 is attached to the frontage. The frontage is formed by an open frame incorporated in the partition, and the vertical rails 12 constituting the open frame are panel side ends. It is fixed to the stud 13 which stands upright. The hanging door device shown in the figure is of a double-opening type, and a door stop pole 15 is attached to the panel 14 and stands upright. Here, in the present invention, the shape of the partition, the structure of the vertical rail 12, and the type of the hanging door device do not matter, but the steady rest roller 7 for guiding the lower end of the hanging door 8 to be opened and closed is arranged near the vertical rail 12.
