PURPOSE:To prevent occurrence of accidents due to inclination by incorporating such a construction that each pallet coupled with a chain makes parallel slide on a slide rail, wherein the horizontal holding member for elevation serves elevating portion, the horizontal holding member for descent serves descending portion, and the bottom surface between the two members serves level motion. CONSTITUTION:A horizontal holding member for elevation 71a at the bottom of each pallet 70 is arranged outside the pallet 70 while a horizontal holding member for descent 71b inside the pallet 70 so that it takes level attitude. Accordingly the pallet 7 makes parallel motion with the aid of a slide rail 72 wherein the horizontal holding member for elevation 71a slides up on the oversurface of said slide rail in the rising portion while the horizontal holding member 71b for descent 71b slides down on the oversurface of the slide rail in the sinking portion. In the level motion portion the oversurface of the slide rail 72 slides on the pallet bottom surface between the two holding members 71 so as to hold the pallet 70 in level and transport it. Thus pallets can always be held horizontal to ensure that transportation be made without risk of spilling- off of fluid substance or causing harm to the objects.
