PROBLEM TO BE SOLVED: To solve a problem that although a belt of a curve conveyor is supported by a trough type roller and drop-off of a conveyed article is prevented, since the trough type roller surface and the belt are always slipped in operation, large slip sound is generated, the surface of the roller is worn and stable operation cannot be performed accompanying with increase of belt tension by slip. SOLUTION: A constitution in which a plurality of free conveyors C aligned in parallel are arranged between the trough type rollers B at front and rear sides of a required curve part in the curve conveyor A, the belt 6 of the free conveyor is brought into contact with a back surface of the belt 1 of the curve conveyor and a meandering prevention means D for ensuring linear traveling of the belts aligned in parallel is provided on the free conveyor is adopted.
