PROBLEM TO BE SOLVED: To provide a curved belt conveyor capable of preventing an endless curved belt from being off a driving unit by avoiding an influence of the oil adhered to a belt surface without providing a projecting material such as a projection in the surface of the endless curved belt. SOLUTION: In the curved belt conveyor structured by wrapping the endless curved belt 3, which is formed into a circular shape with a plane view, over turning members 2 and 2' arranged on both sides in the circumferential direction of a frame 1 formed into a circular shape with a plane view, and for turning the endless curved belt in the circumferential direction, while energizing the peripheral part of the endless curved belt outward in the radial direction with driving mechanisms 4 and 4', lock holes 8 are opened with a constant interval along the periphery of the endless curved belt. A rotary cylinder 9 provided with engaging projections 10 to be detachably fitted in the lock holes 8 in the peripheral surface thereof is arranged freely to be loosely rotate on the same shaft, to which the turning members of both the sides of the frame are fitted, and/or inside the frame.
