PROBLEM TO BE SOLVED: To provide a mechanism for transporting powdered matter evenly and a transport device using it. SOLUTION: The transport device 1 conducts heat treatment while rotating a cylindrical transport device main body 10 and transporting a raw material (a) fed from an inlet end of the transport device main body 10 to an outlet end through an inner part of the transport device main body 10. As a weir part 30 is provided halfway across the inner part of the transport device main body 10, the inner part of the transport device main body 10 is divided into an inlet area A and an outlet area B with the weir part 30 between them. The weir part 30 is equipped with a cylinder body 31 which is co-axial with the transport device main body 10 and has an outer diameter smaller than an inner diameter of the transport device main body 10 and a plurality of stepped blades 35 which is inclined in a direction opposite to the rotation direction Y of the transport device main body 10, as it goes to the material (a) transportation direction X are provided between an inner face of the transport device main body 10 and an outer face of a cylinder body 31.
