It is located on the front side of the surface 22a). By arranging the lower bent portion 31c on the front side of the lower shelf plate 22d in this way, the backward movement of the slide panel 31 is restricted by the front end surface 22a of the lower shelf plate 22d. The forward movement of the slide panel 31 is regulated by the fall prevention bar 24 located at the fall prevention position or the open position as shown in FIG.

In the present embodiment, as shown in FIGS. 4 and 5, a lubricating member 31d made of a resin tape is attached to the back surface of the downward bending portion 31c, which is a surface facing the front end surface 22a. In this way, the downward bent portion 31c and the front end surface 22a are not in direct contact with each other to prevent them from being scratched. Further, the lubricating member 31d can realize a smooth displacement of the slide panel 31.

Further, as shown in FIG. 5, the length dimension H of the portion of the lower bent portion 31c located below the upper surface of the lower shelf plate 22d is the lower shelf permitted by the JIS standard (JIS S 1039: 2005). It is formed with a vertical width dimension larger than the upper limit value of the bending amount of the plate 22d (in the present embodiment, a length of 0.5% with respect to the width dimension of the lower shelf board 22d). As a result, even when the lower shelf plate 22d is bent and displaced downward, it is possible to prevent a gap from being formed between the lower side of the lower bending portion 31c and the lower shelf plate 22d, so that the slide panel 31 is lowered. The front end of the side shelf 22d can keep the state of restricting backward movement.

Further, in the storage shelf 1 according to the present embodiment, the fall prevention bar 24 is attached to the lower shelf plate 22d via the support member 23 as shown in FIGS. 5 to 7. As a result, the fall prevention bar 24 can be assembled to the lower shelf board 22d in advance before the storage shelf 1 is assembled, so that the work at the installation site of the storage shelf 1 can be simplified.

Further, in the case where the fall prevention bar 24 and the support member 23 are assembled to the shelf board bracket 21, it is necessary to remove the fall prevention bar 24 and the support member 23 when attaching or detaching the lower shelf board 22d.
