When the wires 11, 12, 13, and 14 are moved up and down by the winch 10 in the drive mechanism M, the left and right lifting drive units 17 are interlocked with each other in the central chamber 1a and the lifting chamber 2 of the loading / unloading chamber 1, and both left and right stored items are loaded. It can be moved up and down together with the placement unit 18 and stopped in the elevator chamber 2 on each floor for the entry and exit of the automobile 4 with respect to the storage chamber 3.
[0016]
* Turntable 23 in the loading / unloading room 1 shown in FIG. 1 and FIG.
In the floor F of the central chamber 1a among the floors F in the loading / unloading chamber 1, the circular guide rails 21 and the mounting plates 22 inside thereof are lifted up and down trajectories of the left and right storage lifts 15 and 16 of the lift 5. It is provided to avoid the range. The turntable 23 has an intermediate base plate 24 and storage objects mounting bases 25 on both sides in the width direction. The turntable 23 is rotatably supported by a support shaft 26 on the mounting plate 22 at the center of the base plate 24. ing. A plurality of storage object mounting forks 27 (comb-like objects) having a cantilever shape are juxtaposed on both sides of the storage object mounting table 25 in the longitudinal direction.

* Schematic entry / exit operation of multistory parking lot As shown in FIGS. 1 and 2, the turntable 23 is located at the stored item entry / exitable position P and the elevator platform elevating position P. In both the left and right containment lifting platforms 15 and 16, the left and right raising and lowering drive units 17 are stopped at substantially the same height as the floor F surface. Is located in a space between the stored forks 27 of the turntable 23.
[0020]
The automobile 4 is put into the loading / unloading chamber 1 and its wheels 4a are placed on the storage objects mounting table 25 of the turntable 23 on the storage object mounting forks 27 and the left and right storage object storage parts 18 respectively. It is placed on the fork 20 for placing stored items. The driver gets out of the automobile 4 and evacuates from the turntable 23.
[0021]
When both the left and right lifting drive units 17 start to rise together with the left and right stored object mounting parts 18, the respective stored object forks 20 of the left and right stored object mounting parts 18 become the respective stored object forks of the turntable 23. The vehicle 4 is lifted from the space between the two and separated from the space 27, and the automobile 4 is transferred from both the storage object mounting tables 25 of the turntable 23 to the left and right storage object mounting units 18 and mounted thereon. The automobile 4 is placed on the left and right containment elevators 15 and 16 and conveyed to the elevator room 2 on an arbitrary floor, where the left and right containment elevators 15 and 16 are stopped.
