Abstract: A three dimensional parking system (1) includes a plurality of housing stations (X1, Y1, etc.) which are arranged in a vertical direction for accommodating vehicles. A lift compartment (31) is provided adjacent to the housing stations (X1, Y1, etc.). Lifts (4) are vertically movable in the lift compartment while carrying a vehicle thereon. A movable platform (7) carries the vehicle, and is capable of transferring the vehicle to and from the lifts (4). The platform (7) includes drive wheels (9), a drive motor (25) for driving the drive wheels (9), and an energy storage device (19). The energy storage device (19) supplies electrical power to the drive motor (25) when the platform (7) is driven. Therefore, the platform (7) moves between the housing station (X1, Y1, etc.) and the lift compartment (31) under its own ability.
