PROBLEM TO BE SOLVED: To provide a resin molding machine capable of keeping a strength-improving property of a fiber reinforced resin composition by preventing the breakage of a fibrous filler material without generating a backflow of a molten-fiber reinforced resin composition in a cylinder. SOLUTION: The resin molding machine 1 includes a screw 2, a cylinder 3, a hopper outlet 31 and an exhaust port 32 wherein the screw 2 has an axis 21 and a flight 22 installed upright from the outer peripheral surface of the axis 21, and the screw 2 is stored in the cylinder 3, the hopper outlet 31 is set at the base edge 3a of the cylinder 3, and a fiber reinforced resin composition comprising a base resin and a fibrous filler material is supplied from the hopper outlet 31, and the exhaust port 32 is set at the edge 3b of the cylinder 3, and the reinforced resin composition melted and blended in the cylinder 3 is discharged from the exhaust port 32, and a space G between the inner surface 3c of the cylinder 3 and the edge 22a of the flight 22 is larger than 0 but not larger than 0.4% of a diameter D1 of the cylinder 3.
