The stand door 24a is closed by the user H ′ and the cable housing portion 24d is blocked, thereby preventing the electrode portion of the outlet 24c from being exposed to raindrops.

The mechanical parking apparatus 10 shown in FIG. 4 has a pallet lifting body 16 in which a plurality of pallets 12, 13, and 14 are fixed in a vertical line, and is formed in a pit 18 formed by digging down the ground surface GL. It is a so-called elevating type multi-story parking device that is arranged adjacent to each other (two in the example shown, 161 and 162). Each pallet elevating body 161, 162 is provided with an elevating mechanism for elevating vertically, and can be moved up and down independently. Then, the user H operates the switch of the operation panel 20 provided adjacent to the pit 18 to call the target pallet to the ground surface (entry / exit surface) GL to enter / exit the vehicle 22. is there. Normally, the state where the upper pallet 12 is on the loading / unloading surface GL as shown in the drawing is the fixed position in the standby state.
Although a detailed description of the lifting mechanism of the pallet lifting body 16 is omitted, an electric motor, hydraulic pressure, or the like is used as a power source, and a wire or the like is used as power transmission means for lifting the pallet lifting body 16. . (For example, refer to Patent Document 2).

FIG. 5 shows a so-called traverse raising / lowering type three-dimensional parking apparatus, which is another example of the mechanical parking apparatus 10. This mechanical parking device is composed of 4 levels above the ground and 1 level below the ground. The 4th level (uppermost level) and the underground level are lift pallets that can be raised and lowered to the first level above the ground, which is the loading / unloading level. Three 12A and 12E are arranged. These lift pallets 12A and 12E are each provided with a lift drive mechanism. Further, two traversing / elevating pallets 12B and 12C that are traversable and can be moved up and down to the first stage on the ground are arranged on the second and third stages on the ground. The traversing / elevating pallets 12B and 12C are provided with a traversing frame that traverses by traveling on traversing rails with traveling wheels, and the traversing frame is provided with an elevating drive mechanism similar to the elevating pallet 12A. Further, two traversing pallets 12D are arranged on the first level above the entrance / exit plane. The traversing pallet 12D includes a traversing drive mechanism for traveling on traversing rails with traveling wheels. In addition, although the mechanical parking apparatus 10 of FIG. 4 is comprised in 3 rows in the horizontal direction, the number of rows can be increased or decreased as necessary.

In this mechanical parking device 10, when the vehicle is moved in and out of the second to fourth tier lift pallets 12A to 12C and the underground pallet 12E, the first pallet 12D on the ground is retracted transversely. By doing this, a space for one of the lifting pallets 12A to 12C, 12E is secured. Then, the target lifting pallets 12A and 12E are moved up and down to the space formed in the first stage on the ground, or the horizontal lifting pallets 12C and 12D are moved up and down. Therefore, entering / exiting to all pallets including the traversing pallet 12D located at the entering / exiting stage becomes possible. Also, the mechanical parking device 10 is designed to prevent accidental entry of people or vehicles into the mechanical parking device during standby or while completing the movement of the pallet for entry / exit to the first level on the ground. An elevating gate 15 that closes the first stage on the ground is provided (see, for example, Non-Patent Document 1).
The installation of the battery charging stand 24 as described above is also desired for each of the pallets 12A to 12E of the traverse elevating type three-dimensional parking apparatus.
