2. Description of the Related Art In a conventional fluidized shelf, a pair of left and right frames equipped with two columns vertically erected so as to be spaced apart from each other are connected by a connecting rod, and are also formed on opposing surfaces of the left and right frames. A structure is generally used in which one shelf plate having roller bearings arranged on both side edges of the upper surface is attached in an inclined shape with its front lowered by utilizing holes.

When changing the frontage of the fluidized shelves, the lengths of the connecting rods are changed and connected, and the shelves having different lateral widths are replaced and mounted between the left and right frames. It is time-consuming and requires a lot of labor due to the heavy shelves during assembly. Further, in the case where the above shelf boards are mounted in a multi-tiered manner, unless the lower shelf boards project toward the front side than the upper shelf boards and are installed, a container that flows to the front edge of the lower shelf board It takes a lot of effort to take out the tray and the cardboard box, but the conventional structure for attaching the shelf to the frame support is to fix the shelf to the shelf support attached to the support so that it does not slip back and forth. Therefore, it is not possible to easily change the forward protruding length of the shelf board. Further, the adjustment of the inclination angle of the shelf plate cannot be easily changed because the side surface spacing of the shelf plate that contacts the front and rear columns changes.

In Japanese Patent No. 2727420, the left and right frames are made foldable, and narrow shelf shelves are attached to the opposing surfaces of both frames in a vertically multi-tiered manner, and both sides of the container are attached to the left and right shelves. Although a shelf device for mounting and accommodating is described, this shelf device is not a fluidized shelf and the frontage is not changeable. Furthermore, it is not possible to adjust the forward projection length of the shelf board.
