PURPOSE:To surely contain a pallet to be stored in a piled up condition, by the first struts, which support the plural pallets in a condition piling them up spacing a predetermined distance, and the second struts which move the pallet in the piled up condition in the vertical direction. CONSTITUTION:Pallets, which are contained and stored in a condition being piled up spacing a predetermined distance, are supported by the first struts 13a, 13b having no movement in the vertical direction. The pallet, when it moves in the upper direction or in the lower direction by one step of piling, is supported by the second struts 17a, 17b synchronously moving through connection plates 21a, 21b. The first struts 13a, 13b and the second struts 17a, 17b are driven by respective actuators 15a, 15b, 19a, 19b and a driving gear consisting of jacks 20a, 20b. Conveying paths A, B in a range, where the pallet 10 moves, provide no possibility of a lubricant or the like infiltrating into the inside.
