PURPOSE:To make the attitude of pallets to be constant without a guide by arranging one of a pair of chains, which run synchronously in parallel with each other, in such a manner as being shifted by a predetermined distance from the other in the running direction, and arranging pairs of members for rotatably supporting both sides of pallets in an axially shifting manner in conformity with said distance. CONSTITUTION:Second sprockets 10a and 10b are in parallel to the first sprockets 2a and 2b disposed at the same interval between 10a and 10b as that between said first sprockets 2a and 2b, while the first chains 3 and the second chains 11 are respectively stretched between said intervals. The sprockets 10a and 10b are arranged at the position shifted by a preditermined distance (l) from the sprockets 2a and 2b in the running direction. Respective ones of rotatable members 40a and 40b coupled to chains are arranged on both sides of every pallet 30 while said members 40a and 40b are disposed at the same interval as that between the first and the second sprockets in the running direction. Each pallet 30 is thus supported by two points between the chains on both sides so that it is always maintained horizontally even at a reversing part. The interval (l) in the running direction can be varied and therefore a different type of pallet can be selectively used.
