Further, a circulating means is provided for circulating each of the pallet supports in the vertical direction. In addition, when the desired pallet among the above pallets is moved to the uppermost circulation section,
A turning means for turning the pallet at a predetermined angle within a horizontal plane is provided on the loading/unloading section side.

(Function) With the above configuration, in the present invention, a plurality of pallet support stands provided at a predetermined interval in the vertical direction are circulated in the vertical direction by the circulation movement means, and each pallet support stand is moved in a horizontal plane. When a desired pallet among a plurality of vehicle-mounted pallets that are rotatably supported is moved to the uppermost circulation section, it is rotated at a predetermined angle in a horizontal plane by a rotation means provided on the loading/unloading section side of the uppermost circulation section. The vehicle is then entered and exited from the warehouse.

In this way, since each of the above-mentioned pallets is rotatably provided on each pallet support stand, there is no need to arrange a turntable in the vehicle loading/unloading area, and therefore, there is no need to secure space for installing a turntable. As a result, equipment costs will be reduced accordingly.

In addition, since the desired pallet is rotated at a predetermined angle in the uppermost circulation section, the direction of the vehicle can be changed at the uppermost circulation section when entering and exiting the warehouse.
