To provide a curved belt conveyor equipped with a driving mechanism capable of driving and rotating the belt with stability even when oil, water, powder and the like is adhered on the surface of the endless belt.
The curved belt conveyor is 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. One or both of outer peripheral edges of a peripheral side 3a and an inner peripheral side 3b of the endless curved belt 3 positioned between the turning members 2 and 2' are pinched by rotary members 4a to 4c sandwiching the endless curved belt 3 and disposed correspondingly on the upper and lower sides for endlessly rotating, and the endless curved belt 3 is rotated in the peripheral direction by the movement of the pinched locations by the endless rotation of the rotary members 4a to 4c.
