Since the ascending and descending movements of the a and 31b are forcibly synchronized, the ascending and descending vehicle supports 1A to 1C ascend and descend without fear of tilting in the left-right direction. That is, the elevating vehicle support 1A-1
C moves up and down in parallel while maintaining the horizontal posture.

The elevating and lowering vehicle supports 1A to 1C, which have completed the taking in and out of the vehicle, are not immediately raised to the upper vehicle storage level U, but are moved to the laterally moving vehicle supporting base 2 for taking in and out of the next vehicle.
Until the situation where A and 2B have to be moved sideways,
It is desirable to control so that the vehicle is kept waiting at the lower vehicle entrance / exit level D as it is. That is, the elevating vehicle support 1A-
At the time of loading / unloading work with respect to the vehicle 1C, as shown in the flowchart of FIG.
1C, the laterally moving vehicle supports 2A and 2B are driven to make the lower side of the ascending and descending vehicle support for the vehicle loading / unloading work, and if the target position of the lower vehicle entrance / exit level D becomes available, the vehicle The lifting / lowering vehicle support base to be moved in and out is lowered to the lower vehicle entrance / exit level D. Then, when the vehicle is moved in and out of the ascending and descending vehicle support of the vehicle entering and exiting work, which has been lowered to the lower vehicle entrance / exit level D, the drive command of the next laterally moving vehicle supports 2A and 2B is input. The elevating and lowering vehicle support stand, which has been completely taken in and out of the vehicle, is left at the lower vehicle entrance / exit level D.
