ABSTRACT:
A curved conveyor is provided which includes at least a pair of supports arranged so that their axis lines mutually intersect at a desired angle, and an endless curve belt having a flat fan shape matching the angle which is supported on the respective supports so as to be able to run. An endless drive chain is formed along the outer circumference of the curved belt to be bendable in a running direction and in a direction orthogonal to the running direction by connecting multiple unit members to each other. Connecting members connect the unit members of the drive chain to the outer circumferential portions of the curved belt corresponding to the unit members, such that a driving force by the drive chain is applied to the outer circumferential side of the curved belt so as to run the curved belt in a curved manner at a desired angle.
