Normal continuous operation of traversing and leaving one or more of the multiple self-propelled carriages on the circulation rail, other self-propelled carriages were evacuated to the sub-parking space, and left on the circulation rail. The self-propelled trolley is circulated preferentially for partial circulation operation.Therefore, by selectively using these operations according to the entry / exit situation of the vehicle, the self-propelled trolley can be moved efficiently. It is possible to smoothly load and unload cars. In addition, since each self-propelled trolley is self-propelled individually, a small driving force is required, and there is an advantage that noise generation can be suppressed to a low level.

According to the second aspect of the invention, each inner wheel of each self-propelled carriage travels on the inner rail, and each outer wheel travels on the outer rail along the tracks of its straight and curved portions. Therefore, each self-propelled carriage can circulate on the circulation rail without largely protruding outward, and it is possible to prevent a dead space from occurring in the installation space.

Further, according to the third aspect of the invention, since each self-propelled carriage is circulated in a plane between the circulation rail and the pair of auxiliary rails on the sub-parking space, the self-propelled carriage can be circulated on the circulation rail. By combining the circulation and the planar circulation, it is possible to set various movement patterns of the self-propelled carriages as a whole, and it is possible to further improve the smoothness in the loading / unloading operation of the vehicle.

Further, according to the structure of claim 4, the inner wheels on the driving side of each self-propelled carriage are made to travel on the curved portion of the inner rail at the same movement pitch as on the straight portion.
Each self-propelled trolley can be fast-forwarded in a small trajectory while maintaining a constant speed at the curved portion of the circulation rail, and it is possible to avoid mutual interference by maintaining a constant distance between each self-propelled trolley in front and behind, Each self-propelled carriage can smoothly run on the circulation rail.

According to the fifth aspect of the present invention, the vehicle has a single loading / unloading port installed inside or outside the circulation rail so that the loading / unloading port of the automobile and the circulation rail do not interfere with each other. The self-propelled trolley can be constantly circulated on the circulation rail even when the vehicle is being transferred between the exit and circulation rails, and the entry and exit ports of the vehicle are divided into the entry and exit ports and face each other. However, when a car that moves forward from the entrance moves from the outward path to the return path due to the circulation on the circulation rail, the direction of the car is reversed from the direction at the time of storage, so when exiting, this reversed direction Since it is transferred to the exit port, it is possible to enter and exit the vehicle forward without using a special device such as a turntable.
