PURPOSE: A powder transfer apparatus is provided to efficiently transfer powder by generating uniform suction force over the entire circumferential surface. CONSTITUTION: A powder transfer apparatus comprises an outer case(30), an inlet side end plate(10), an outlet side end plate(40), and an inner case(20). The outer case has a high pressure hose connector(32) on the exterior. The inlet and outlet side end plates are mounted on both ends of the outer base and have an intake hole(11) and a discharge hole(41), respectively. The inner case is built in the outer case, the inlet side end of the inner case is connected to the inlet hole of the inlet side end plate, and a gap(G) is formed on the entire circumferential surface between the outlet side end of the inner case and the rear part of the high pressure hose connector. A diameter-reduced part(31) is formed in the rear part of the high pressure hose connector of the outer case so that the gap is located at the end of the diameter-reduced part.
