PROBLEM TO BE SOLVED: To provide an apparatus for manufacturing a hydraulic inorganic curing material capable of satisfactorily sucking and dehydrating a molding without necessity of an excess power for rotatably driving a suction box without operating an excess load in the case of pressure reducing. SOLUTION: A suction means of the apparatus for manufacturing the hydraulic inorganic curing material has the suction box 6 including a suction surface 62 having suction holes 63 and a suction chamber 61 having a communicating opening 65, and a pressure reducing device 5 having a receiving surface 55 for receiving the box 6 from below, and a pressure reducing chamber opening 52 for communicating a pressure reducing chamber 54 through the opening 65 provided at the surface 55. In this case, the opening 65 is provided at a center in a lateral direction. Then, a maximum length of the opening 65 in the lateral direction is set to 50% or less of the width of the surface 62.
