PROBLEM TO BE SOLVED: To provide a flight conveyor capable of preventing the possibility that full powder and granular material fed between adjacent flights overflows by the vibration during the transport or the vibration of the flights, held between the flights and a case, and a space between the flight and the case is firmly blocked by the powder and granular material when a chain with the flight travels in the case. SOLUTION: The flight conveyor is provided in a case to communicate a throw-in port at a low position with a discharge port at a high position in a circulating manner between an endless chain transport side and a return side, while a traveling passage of the flight mounted on the transport side endless chain is formed of an inner face of the case and an inner face of a bottom plate. The flight consists of a main flight and a collapsible sub flight, a collapsible means is provided in the traveling passage of the sub flight in the case in the vicinity of the throw-in port, and a lower edge of a throw-in cylinder faces inside the traveling passage of the sub flight.
