Summary:PROBLEM TO BE SOLVED: To provide a molding machine which can prevent a foreign substance from being included into a molded object. SOLUTION: This molding machine capable of forming the molding object comprises a cylinder 21 and a screw 25 which is housed inside the cylinder 21 in the way the screw 25 is movable in the longitudinal direction of the cylinder 21 and extrudes a resin material 200 supplied from the rear end part 21a side of the cylinder 21 from the apex part of the cylinder 21. In addition, the cylinder 21 has an exhaust port 21c formed for exhausting an internal gas and a dust-preventing device 29 that prevents a foreign substance from flowing into the cylinder 21 from a gap 21e between the cylinder 21 and the screw 25 following the exhaust of the gas from the exhaust port 21c.
