PROBLEM TO BE SOLVED: To provide a pipe conveyer capable of smoothly varying the shape of a conveyer belt 1 in a moving region. SOLUTION: Supposing the length of the moving region is denoted by L, the length from the end of a plane-shaped side in the moving region to guide rollers 8 is denoted by X, the radius of the conveyer belt 1 rounded in a pipe shape is denoted by R, and the radius of an inscribed circle inscribed on the outer circumferential surfaces of three or more guide rollers 8 is denoted by Y, the purpose is achieved by satisfying the relations of Y=k×R×L/X and 0.6<=k<=1.5.
