PROBLEM TO BE SOLVED: To prevent a vibration by upgrading an overall weight balance. SOLUTION: A servo motor 4 for a screw for rotating an injection screw 3 is fixed to a center of a lateral upper part of a movable plate 2. Servo motors 7 for injection for advancing the screw together with the plate 2 by operating threaded mechanisms are fixed at an equal interval to right and left sides of the motor 4 of the plate 2. Accordingly, a center of the overall gravity is located at a center of the motor driven injection molding machine without displacing to right or left with good balance, and in any of the cases of plasticizing and injecting, its vibration is suppressed to a small value as much as possible.
