Further, as shown in FIGS. 4 to 6, a screw screw 6 in which the pitch P ₁ of the screw in the middle portion is the smallest and the pitches P ₂ and P ₃ in the upper and lower portions are gradually increased is provided in each of the columns 3A, 3
B, 3C and 3D are rotatably provided respectively. Further, as shown in FIG. 3, screw screws 7 having an equal pitch are rotatably provided in the horizontal beams 4A and 4B, respectively.

Further, as shown in FIG. 2, the four corners of the vehicle-mounted pallet 8 formed in a rectangular plane shape on which the vehicle 2 can be mounted are respectively joined to the blades 6a of the screw screws 6 to rotate the screw screws 6. A pallet support roller 9 that rotates in accordance with the above is provided. Further, brackets 10 are provided so as to project above and below the central portion of the front and rear edges of the pallet 8, respectively, and the horizontal beams 4A and 4B are provided from these brackets 10.
A transverse feed roller 11 is provided which is joined to the blade 7a (see FIG. 3) of the screw screw 7 inside and rotates as the screw screw 7 rotates.

The on-vehicle pallet 8 moves up and down via the pallet support roller 9 by the rotation of the screw screw 6,
3 and 4 show a state in which the pallet 8 reaches the lower limit, in which case the pallet support roller 9 is joined to the upper surface of the slide guide 12 juxtaposed with the horizontal beam 4B. Roller 11 for horizontal feeding below the pallet 8
Engages with the blade 7a of the internal screw screw 7 through the notch 13 provided on the upper side of the horizontal beam 4B.

Therefore, when the screw screw 7 rotates, the pallet 8 is transferred to the pallet 8 via the lateral feed roller 11 as shown in FIGS.
In the direction of arrow G in FIG. 3, the pallet bearing roller 9 rolls on the upper surface of the slide guide 12 after passing through the notch 14 provided at the side edge of each column. And pallet 8
3 reaches the right end in FIG. 3, the pallet bearing rollers 9 and 9 engage with the screw screws 6 in the columns 3C and 3D, respectively, and the lower traverse roller 11 is provided on the upper side of the horizontal beam 4B. It is located directly below the notch 13.

Therefore, when the screw screw 6 is rotated in a predetermined direction in this state, the pallet 8 is moved to the arrow H in FIG.
As shown in FIG. FIG. 5 shows a state in the middle thereof, and FIG. 6 shows a state in which the pallet 8 reaches the upper limit. In this case, the roller 11 above the pallet 8 has a notch 13 provided at the lower side of the horizontal beam 4A. Through which the pallet bearing roller 9 engages with the screw screw 7 in the horizontal beam 4A and slides on the same level as the lower edge of the notch 14 provided on the side edge of the columns 3A, 3B, 3C, 3D. It is located on the same level as the upper surface of the guide 15.

When the screw screw 7 is rotated in a predetermined direction in that state, the roller 11 is pushed by the screw screw 7 and the pallet 8 moves in the direction of arrow I in FIG.

This is the pillars 3A, 3B, 3 of the device of the present invention.
Since the pitch P _{1 of the} middle portion of the screw screws 6 provided in C and 3D is the smallest and the pitches P ₂ and P ₃ of the upper and lower portions are gradually increased, each pallet 8 is fed into the screw screw 6 at equal intervals. As shown in FIG. 8, if the vertical sectional areas occupied by the respective vehicles placed on the respective pallets are indicated by blocks A to B, a space S ₁ between B and B and a space S ₄ between B and E can be obtained. Becomes large, but in the middle blocks,
The gaps S ₂ and S ₃ between the _{two become} smaller.

The intervals S ₁ and S ₄ are required to be large to some extent in order to laterally move the vehicle, but the intervals S ₂ and S ₃ between the intermediate blocks B, C and D are as shown in FIG. The minimum gap that does not interfere with each vehicle 2 is sufficient. Therefore, in the conventional parking device having a height of 8 m as shown in FIG. 7, the number of vehicles that can be parked is 7, but according to the present invention, a parking device having a height of 8 m is used as shown in FIG. It is possible to park 10 vehicles.
