2. Description of the Related Art There are many gondola type multi-level parking devices in which a plurality of pallets for loading automobiles are mounted on an endless chain conveyor, and the endless chain conveyors are circulated to efficiently store a large number of automobiles in a narrow space. Although proposed, the conventional multi-level parking apparatus has a pallet rotatably attached to an endless chain conveyor because of its structure.However, when the wind is strong, the pallets sway significantly and interfere with each other. Or, in the worst case, a car loaded on a pallet may fall, and there is a drawback of lacking stability.

In order to prevent the pallet from shaking, a guide roller is provided at one end of the pallet and fitted into a guide rail to prevent the pallet from shaking, which has been proposed and put to practical use. However, since the improved product also has only one guide roller for preventing the shake, it is not always a perfect shake preventer and there is room for improvement.

Further, at the position where the support shaft for supporting the pallet on the endless chain conveyor intersects with the guide rail as it circulates, the guide rail is notched, and the guide roller makes the notch. When passing, the pallet does not have an anti-sway action, so the pallet may sway at this position.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to eliminate the above-mentioned drawbacks of the prior art, and its object is to provide a double guide rail composed of an outer ring guide rail and an inner ring guide rail. By fitting the two guide rollers mounted on the left and right sides of the pallet to the respective guide rails one by one, the two guide rollers are constantly fitted to the double guide rails and circulated. By firmly guiding the pallet, even if the car is loaded in a slightly biased state, the pallet can always be maintained in a horizontal state, and it is possible to completely prevent shaking due to external factors such as strong wind. Yes, this also enhances the horizontal stability of the pallet and eliminates the risk of the car falling under any circumstances. .

Another object of the present invention is that even if one guide roller reaches the notch of the guide rail and is not guided by the above structure, the other guide roller is always fitted to the guide rail to guide the pallet. The pallet eliminates the section not guided by the guide rail, and the guide roller separated from the guide rail in the cutout portion is surely fitted to the guide rail again. This is to prevent the rollers from accidentally coming off the guide rails and to enable extremely stable circulation of the pallets.

Still another object is to connect the outer ring guide rail and the inner ring guide rail to each other, and to provide two guide rollers fitted to the guide rail from the outer ring guide rail to the inner ring guide rail and from the inner ring guide rail to the outer ring. By making the pallets movable to the guide rails, it is possible to smoothly circulate the pallet while the two guide rollers are always fitted to the double guide rails.
