PROBLEM TO BE SOLVED: To provide a low-cost device reducing the machining cost for components and the number of assembling stages by reducing the number of part items. SOLUTION: A connecting hole provided in a pallet base 1 and a connecting block attached to a chain 8 are engaged with each other so as to connect the chain to the pallet base. The connecting hole provided in the pallet base is formed a little larger in the advancing direction of the pallet compared with the connecting block, and the pallet base is connected to the chain in a floatable state, so that the pallet, the connecting part of the chain, and a floating mechanism part can be constituted of the same component, thus reducing the number of part items.
