A return pipe conveyer including an endless conveyer belt supported between opposing rollers, support rollers for supporting the belt and an object to be conveyed during a conveying trip of the belt, shape supporting rollers for rounding the belt into a substantially pipe-shaped cross section during a return trip of the belt, and pressing units for pressing opposite lateral edges of the belt against the supporting rollers to suppress warping of the belt caused by the shape supporting rollers during the return trip, thereby ensuring smooth and stable movement of the belt during the conveying trip.
