Specifically, as shown in FIG. 16, even when the second-stage box pallet 4 is unloaded with respect to the first-stage box pallet 4 in a state where it is horizontally displaced from a predetermined mounting position. The inclined lower surface 40 of the guide plate 36 of each guide member 30 of the second-stage box pallet 4 comes into contact with the inclined upper surface 50 of the guide plate 48 of each receiving guide member 46 of the first-stage box pallet 4 to guide it. To be done. As a result, as shown in FIG. 17, the lower surface of the frame means (horizontal frame 14 in the illustrated example) of the second-stage box pallet 4 is changed to the frame means of the first-stage box pallet 4 (horizontal frame in the illustrated example). 44), and the second-stage box pallet 4 is stacked at a predetermined position on the first-stage box pallet 4.

When the second-stage box pallet 4 is stacked on the first-stage box pallet 4, each guide member 30 of the second-stage box pallet 4 and each corresponding receiving member of the first-stage box pallet 4 Between the guide member 46 and the guide member 46, the horizontal movement of the second-stage box pallet 4 with respect to the first-stage box pallet 4 is restricted. Specifically, as shown in FIG. 17, the inclined lower surface 40 of each guide member 30 of the second-stage box pallet 4 is the upper inclined surface of each corresponding receiving guide member 46 of the first-stage box pallet 4. It is configured so as to be positioned substantially in parallel with the upper side of 50 or with a predetermined gap therebetween.

As described above, the box pallets 4 can be stacked three-dimensionally by using the forklift. In addition, they can be arranged side by side in the horizontal and vertical directions. Since the box pallets 4 are formed on a rectangular parallelepiped, the box pallets 4 adjacent to each other are closely arranged with almost no space.

The present invention has been described above in detail based on the embodiments, but the present invention is not limited to the above embodiments, and various modifications or modifications can be made within the scope of the present invention. It is a thing. For example, by changing the shape of the floor board 16 of the floor 8 of the box pallet 4 and the like, it can be used for storing things other than vehicles (for example, small boats such as boats and yachts). This device also includes them.
