Has been formed. By inserting the guide roller 6 into the vertical groove 7, the pallet 3 is supported so as to be vertically movable with respect to the columns 2a, 2b, 2c, 2d. Further, hydraulic cylinders 8 and 9 are erected on both sides of the pallet 3 on the base 1, and the tips of the rods 8a and 9a of the hydraulic cylinders 8 and 9 are connected to the frames 4 and 5, respectively. It is fixed at the top of. As a result, if the rods 8a and 9a of the hydraulic cylinders 8 and 9 are sucked from the state shown in FIG. 1, the pallet 3 can be lowered toward the base 1.

As shown in FIGS. 1, 2, and 4, the pallet 3 is provided with a rectangular cut 11 at its rear part, and the two rollers 1 are formed in the cut 11.
2 and 13 are provided horizontally along the width direction of the pallet 3. Here, the rollers 12 and 13 are in a state in which only rotation in one direction (counterclockwise direction in FIG. 2) is allowed, and rotation in the opposite direction is locked.
A hydraulic pump 14 is attached to the rear portion of the pallet 3, and the hydraulic pump 14 is connected to the roller 13 via a chain 15. As a result, the drive wheels (rear wheels in this embodiment) 16 of the vehicle are set to the roller 1
When the drive wheels 16 are rotated in the clockwise direction in FIG. 2 while being mounted on the rollers 2 and 13, the rollers 12 and 13 rotate counterclockwise. Therefore, the rotation of the rollers 13 is transmitted via the chain 15 to the hydraulic pump. 14 can be transmitted. As shown in FIGS. 1 to 3, the hydraulic pump 14 is connected via a hydraulic rubber hose 10 to a hydraulic unit 18 including an ascending / descending speed adjusting valve, and the hydraulic unit 18 is connected to the hydraulic cylinders 8 and 9.

As a result, the pallet 3 having the vehicle 19 mounted thereon rises along the columns 2a, 2b, 2c, 2d to the position indicated by the solid line in FIG. After the first vehicle 19 is parked in this way, the second vehicle is parked on the base 1. As described above, since the pallet 3 is raised by the rotational force of the drive wheels (rear wheels) 16 of the vehicle 19, no power source is required unlike the conventional case, so that the pallet 3 can be easily installed at any place. It can be done and does not require electricity charges. Next, pallet 3
When moving the vehicle 19 parked on the outside, first, the vehicle parked on the base 1 is moved to the outside. Then, the operating lever 17 is operated to gradually release the pressure in the hydraulic cylinders 8 and 9 to thereby obtain the rods 8a and 9a.
Inhale. Then, the pallet 3 descends. When the pallet 3 is lowered onto the base 1, the vehicle 19 mounted on the pallet 3 is moved to the outside. In this case, the rotation of the rollers 12 and 13 in the clockwise direction in FIGS. 2 and 4 is locked, so that when the vehicle 19 is moved forward (in this case, the drive wheels 16 are in the opposite direction to the arrow A in FIG. 4). The rollers 12 and 13 do not rotate,
As a result, the vehicle 19 can be smoothly moved to the outside of the pallet 3.

In the above embodiment, the roller 1
Although the rollers 2 and 13 are provided at the rear of the pallet 3, the rollers 12 and 13 are not necessarily provided at the rear of the pallet 3, and the rollers 12 and 13 may be provided at the front of the pallet 3 and other mechanisms may be configured to correspond thereto.
