The base panel 4 is positioned and fitted by the protrusion 51 between the left and right side portions 21c and 21d of the back panel 2 and the rear side portions 31d and 31d of the side panels 3R and 3L.
Are positioned in the front-back direction.

According to the above embodiment, the back panel 2
The protrusions 51 that rotatably fit into the left and right engaging spaces A by using the front-rear spacing L formed by the connecting tools 6U and 6D formed in the connecting portions of the side panels 3R and 3L as the engaging spaces A. Since the base panel 4 is provided with,
There is no need for member mounting work or processing for forming the connecting portion between the base panel and the back panel, the number of parts can be reduced, and the manufacturing cost can be reduced. Also,
By forming the front-to-back width w of the projecting piece portion 51 so as to be in contact with or close to the front-to-back space L of the engagement space A, the base panel 4 in use can be positioned and fixed at a fixed position in the front-rear direction. Also, by tilting the base panel downward from the upright state, the regulating inclined portion 52 is abutted against the rear side portions 31d of the left and right side panels 3R and 3L, and the base panel 4 is positioned at a fixed position in the left-right direction. It can be held by removing the rattling. further,
The curved surface portion 51r formed on the bottom surface of the protruding piece portion 51 allows the base panel 4 to be smoothly flipped up and fallen.

5 (a) and 5 (b) show a modified example of the projecting piece portion 51. As shown in FIG. That is, the protrusion 61 is rotatable about the rotation axis within the front-rear space L of the engagement space A, and the front and rear of the base panel 4 are opened with a slight gap (or in a sliding contact state). Front and rear width w (w ≦
L) has a bottom portion 61a and an upright portion 61b that is erected upward from the front portion of the bottom portion 61a to form an L-shaped cross section. Then, as shown in FIG.
The rotation restriction length h connecting the upper front corner of the standing portion 61b and the bottom rear corner of the bottom portion 61a is configured to restrict the rearward rotation of the base panel 4 at the standing limit. Further, a curved surface portion 61r is formed in the rear corner portion of the bottom portion 61a along the rotation direction, and the standing portion 6 is further formed.
Curved surface portion 61s along the rotation direction at the rear corner portion of 1b
The curved surface portions 61r and 61s are formed on the left and right side portions 21 when the base panel 4 is flipped up and falls.
It is configured so as to be in sliding contact with the c and 21d and rotate smoothly.

According to the above-described embodiment, when the base panel 4 is flipped up to stand up during nesting, the rotation restricting length H formed on the projecting piece 61 prevents the base panel 4 from falling backward. At the same time, it is possible to hold the protruding piece 61 and prevent the base panel 4 from rattling. Therefore, the noise during the transportation in the folded state can be reduced and the robot can be moved stably.

Further, FIGS. 6A to 6C show another modified example of the projecting piece portion, and as shown in FIG. 6A, a circular shape having the front-back width of the engagement space A as a diameter. The protruding piece 71 of the cross section,
As shown in FIG. 6 (b), a projecting piece 72 having an oval cross section whose minor axis is formed to have the same thickness as that of the base panel 4, FIG. 6 (c).
Alternatively, the protrusion 73 may have an elliptical cross section whose short diameter is equal to the thickness of the base panel 4.

In the above embodiment, the projecting piece portions 51,
Although the connecting tool 6D is used as a measure for preventing the disengagement of 61, a separate retaining member may be attached. Further, although the base panel 4 is shown as the planar member, it may be a shelf panel or a ceiling panel, and the material thereof may be made of metal or wood in addition to the composite of resin and metal. it can. Furthermore, the form may be a mesh or a frame.

Further, the rear member is the back panel covering the back surface and the side member is the side panel covering the side surface.
The shape is not limited to the panel shape (plate shape), and may be a frame-like body or a net-like body, or may be a component such as a shelf installed integrally adjacent to the storage tool.
