A multi-deck parking structure includes a plurality of decks for storing pallets constructed to carry vehicles, respectively, an entrance section for receiving and delivering vehicles, and a movable unit for moving upward and downward through a vertical shaft extending laterally of the decks into the entrance section, to transport the pallets between the entrance section and the decks. The movable unit has pallet supporting fork assemblies extendible to and retractable from the decks, and footpath floors for allowing a person to walk thereon. The footpath floors are vertically movable relative to the pallet supporting fork assemblies. The entrance section includes an adjusting device for keeping the footpath floors substantially level with floor surfaces of the entrance section and supporting surfaces of the pallet supporting fork assemblies when the movable unit is placed in the entrance section, and lowering the footpath floors below the supporting surfaces of the pallet supporting fork assemblies when the pallet supporting assemblies are in a position to extend to or retract from the decks.
