PROBLEM TO BE SOLVED: To provide a curve conveyor not requiring a belt retaining mechanism and to facilitate maintenance management while reducing cost of the curve conveyor. SOLUTION: A curve belt 13 is laid on a drive tapered roller 11 and a driven tapered roller 12 and is stretched in a fan shape. An inner peripheral length, i.e., length of an inner peripheral side P2 of the curve belt 13 is made shorter than an inner peripheral length geometrically specified by a central angleαof the curve belt 13 stretched in the fan shape, a taper angleθof the tapered rollers 11, 12, a radius R2 to the belt inner peripheral side P2 and a radius R1 to a belt outer peripheral side P1 by 0.3-0.5%.
