PROBLEM TO BE SOLVED: To provide a molded product ejector capable of being made lightweight and small-sized by simplifying the structure of a drive mechanism for moving a chuck part, and also capable of shortening a molded product ejection cycle by reducing the weight of a movable member. SOLUTION: The chuck part for holding a molded product is moved in a predetermined direction to eject the molded product from a molding machine. The drive member for moving the chuck part is fixed to the movable part provided with the chuck part and is constituted of the shaft-shaped stator fixed to the movable part provided with the chuck part and provided with a large number of electromagnet polar teeth, each of which has a coil wound around the outer peripheral surface thereof, at a pitch corresponding to moving resolving power, and of the cylindrical movable element supported on the outer periphery of the shaft-shaped stator in a rotatable manner and having permanent magnet polar teeth corresponding to the electromagnet polar teeth provided to the inner peripheral surface thereof and also having a power transmission member provided to the outer periphery thereof.
