There is a problem that dirt is attached to the place and the dirt is noticeable. Therefore, when the cradle 2 is made of wood, such a problem can be solved by coating the surface of the cradle 2 with a metal plate such as stainless steel or aluminum.

  FIG. 7 is an explanatory view showing a hanging tool for supporting the cradle. At the upper end of the columnar part 4a, an engaging part with the connecting plate 4c is provided. As shown in FIG. 7B, the connecting plate 4c is composed of a cylindrical portion in which a thread is formed and a rectangular column portion 4d in which a through hole 4d having a hexagonal cross section is formed. The cylindrical part in which the screw thread is formed corresponds to the fixing part 4 b of the stopper 10. As shown to Fig.7 (a), the through-hole 4e corresponding to the through-hole 4d of the hexagonal cross section formed in the connecting plate 4c connected to the columnar part 4a is formed. In this example, the cross-sectional shape of the columnar part 4a is rectangular. A plurality of through holes 4d formed in the connecting plate 4c and a plurality of through holes 4e formed in the columnar portion 4a are arranged in the vertical direction. FIG. 7C shows a fixing pin 4f having a hexagonal cross section. The fixing pin 4f is inserted into the through hole 4d and the through hole 4e and engages the columnar portion 4a and the connecting plate 4c. In addition, in the fixing | fixed part with the cradle 2 of the lower end part of the columnar part 4a, the shape of the columnar part 4a may be a rectangular shape, and may be a column shape like an upper end part.

  The columnar portion 4a is shifted in the vertical direction to align the through hole 4d formed in the connecting plate 4c with the through hole 4e formed in the columnar portion 4a, and the fixing pin 4f engages the columnar portion 4a and the connecting plate 4c. To do. In this case, the size of the space portion in the vertical direction of the chair storage unit 3 expands and contracts according to the thickness of the seat plate 12 of the chair. For this reason, according to the thickness of the seat board 12, it can respond to what kind of seat board thickness by adjusting the space part of the chair storage part 3 suitably.

  In the example of FIG. 7, since the cross-sectional shapes of the through hole 4d, the through hole 4e, and the fixing pin 4f are hexagonal, there is an advantage that the connecting plate 4c and the columnar portion 4a can be stably engaged. However, the cross-sectional shape of these members is not limited to a hexagon, and can be selected as appropriate, such as a circle or a rectangle.

  FIG. 8 is an explanatory view showing a stopper. In FIG. 8, the connecting plate 4c described in FIG. 7 is omitted, and the cross-sectional shape of the columnar portion 4a is circular. As described above, the upper end portion of the columnar portion 4a is provided with the fixing portion 4b in which a thread is formed. As shown in FIG. 8B, the stopper 10 is formed with a screw hole 10a and engages with the fixing portion 4b.
