When the pressing body 85 slides backward by the guide rod 81 and engages with the second limit switch 83b by retracting the pressing rod 76, the first and second driving mechanisms ( 64, 73 stop operation, the pallet 37 is held in position on the bogie 44 of the lifter 41, the pair of friction difference 57, 57 ' The outer end of the guide plate 39 of the pallet lower surface is sandwiched and supported. When the empty pallet 37 is transferred and placed on the lifter 41 in this way, the lifter 41 is lowered and held at the lower end. When the lifter 41 is held at the lower end, the pressing rod 76 retracted from the second driving means 73 protrudes, and the movable table 54 is protruded by the protrusion of the pressing rod 76. While moving forward along the guide rails 53 and 53 ', the pressing body 85 slides along the guide rod 81 and engages with the third limit switch 83c. Then, the second ball mechanism 73 stops operation, and the pair of frictional differences 57, 57 'is shown in FIG. 9, so that the guide plate 39 of the pallet 37 Apart from the outer end, the guide plate 39 of the pallet 37 accommodated in the pallet 37 on the trolley 44 and the lowermost garage 32 approximately midway between the forward end position and the retracted end position. It is held at an intermediate position between and. In this state, the vehicle A on the turntable 35 is intruded into the structure 31, and the moving stops on the pallet 37 on the trolley 44. When the vehicle A is loaded into the pallet 37, the pallet 37 is bent. And when the motor vehicle A is mounted on the pallet 37 on the trolley | bogie 44, the pressing rod 76 of the 2nd drive means 73 will retract. When the pressing body 85 slides backward along the guide rod 81 by the retraction of the pressing rod 76 and engages with the second limit switch 83b, the second driving mechanism 73 is operated. And the friction differentials 57 and 57 'are positioned at the retreat end position, and hold the outer end of the guide plate 929 on the lower surface of the pallet again. In this way, when the friction wheels 57 and 57 'are maintained in the original retreat end position, the lifter 41 of the garage 32 in which the pallet 37 on which the vehicle A is placed is originally accommodated. Raise to height. And the trolley | bogie 44 of the lifter 41 opposes the desired garage 32, The fixed rails 34 and 34 of this garage 32, and the 2nd guide rail 34 of the trolley | bogie 44 are carried out. When () and (34) are kept on a straight line in the same horizontal plane, the first and second drive mechanisms 64 and 73 operate. Then, the drive gear 67 of the drive motor 65 rotates, and the pressing rod 76 protrudes, and the mating friction differentials 57 and 57 'rotate forward in the pallet unloading direction. As the friction wheels 57 and 57 'are advanced, the guide plate 39 on the lower surface of the pallet sandwiched between the friction wheels 57 and 57' is provided with friction wheels 57 and 57. ') Is conveyed outward by the frictional force generated by the rotation, and as a result, the angular ring 38 of the pallet 37 moves from the second guide rails 46, 46 of the trolley 44. The pallets 37 are transferred to the garage 32 by replacing them with the fixed rails 34, 34 of the garage 32. Then, when the pressing body 85 slides forward along the guide rod 81 by the protrusion of the pressing rod 76 and engages with the first limit switch 83a, the first and second driving mechanisms (64) and (73) stop operation, the pallet (37) is held in position at the garage 32, and the paired friction differences (57) and (57 ') of the pallet lower surface The inner end of the guide plate 39 is held. In this way, when the motor vehicle A is accommodated in the desired garage 32, the press rod 76 of the 2nd drive means 73 retracts, and by the retraction of this press rod 76, the friction difference 57 At the same time, when 57 and 57 'are removed from the guide plate 39 on the bottom surface of the pallet, the pressing body 85 engages with the second limit switch 83b, and the carriages 57 and 57' are retracted. Will be in the original position of the atmosphere. Hereinafter, the vehicle A is moved in and out in the same manner.

In addition, the above embodiment has been described in the case of applying to a lifter installed in a building such as a parking tower, but the present invention is not limited thereto, and may be applied to a lifter installed in a receiving rack.

According to the present invention, the stroke dimensions in the forward and backward movements of the paired friction wheels are very short, the structure is simple, the size can be reduced, and the pallet can be made faster and lower in noise. In addition, as in the prior art, it is not necessary to attach a support rail for supporting the seating device in each garage, and manufacturing is easy, and the manufacturing cost can be drastically reduced.
