PROBLEM TO BE SOLVED: To improve control response, control precision, control accuracy and control stability due to stiffening, while contributing to downsized miniaturization of molding machine body and noise reduction; and to solve the problem of unbalanced load to a rotor shaft of a servomotor. SOLUTION: An injection molding machine M has a direct connection structure 8, in which the end of a nut section 6 and the end of a rotor shaft 7 are linked directly, by regulating relative revolution of the nut section 6 to the rotor shaft 7 with a regulator 12. The above is achieved by inserting the end of the nut section 6 of a ball screw mechanism 4, which drives a moving plate 104 back and forth, to a recess 11 formed in axial direction from the end face of the rotor shaft 7 of a servomotor 3; wherein the injection molding machine is equipped with a driving mechanism 1, which drives the moving plate 104 of a mold closing device Mc as a moving part 2 back and forth by means of the servomotor 3 and the ball screw mechanism 4.
