Therefore, in the three-dimensional parking apparatus 1, it is possible to improve the load resistance of the lowermost pallet 4c itself while avoiding the concentration of the load on the face plate 12 of the lower pallet 4c.

  Further, since the front cross member 13 is also integrally provided with a balance chain sprocket 27 that meshes with the balance chains 10 and 11, when an upward load F2 is applied by the balance chains 10 and 11, the pallet lifting body The torque T2 generated between the load 3 and the downward load W can be received by the front cross member 13 of the lower pallet 4c in a concentrated manner.

  Thus, in the multi-story parking apparatus 1, since the high rigidity is not requested | required of the face plate 12 itself of the lower pallet 4c, it is possible to use a thin plate for the face plate 12. That is, as described above, it is possible to assemble the face plate 12 of the lower pallet 4c by fastening the bolts and nuts between the rail plate 16 and the connecting plate 17, and obtain sufficient load resistance while reducing the weight of the face plate 12. It becomes possible. Further, in this case, the face plate 12 before assembly can be divided into three rail plates 16 and 16 and a connecting plate 17. Thereby, the handling of the face plate 12, which tends to be large, can be facilitated, and the transportability of the three-dimensional parking apparatus 1 to the assembly site can be improved.

  Further, in the multi-story parking apparatus 1, bolt-nut fastening is also employed for fixing the cross members 13, 14 and the face plate 12 and fixing the cross members 13, 14 and the pallet columns 6, 7. Thereby, the assembly work of the pallet elevating body 3 can be facilitated on site. Therefore, unlike the case where welding is used for assembling the pallet lifting / lowering body 3, the skill of the assembling work hardly depends on the skill level of the operator.

  The present invention is not limited to the above embodiment. For example, the connection between the cross members 13 and 14 and the pallet columns 6 and 7 is not limited to bolt-nut fastening, and may be fastened by rivets or fastened only by bolts. Similarly, in the face plate 12, the rail plate 16 and the connecting plate 17 may be connected by rivets or by only bolts. Even when such a fastening method is employed, the same operational effects as in the case of bolt-nut fastening can be obtained.
