PROBLEM TO BE SOLVED: To provide an injection molding machine in which cost can be reduced by curtailing the number of components and simplifying the mechanism. SOLUTION: One end of a screw spline shaft formed to make a helical groove for ball screw mechanism and a straight groove for a ball spline mechanism cross is fitted to the side of a fixed die plate. A nut body which is screw-bonded to a screw spline shaft and to which the rotation of a servo-motor for a nozzle touch is transmitted is held rotatably by a holding board holding the root part of a heating cylinder, and a spline outer cylinder spline-bonded to the screw spline shaft is fitted to the holding board. The root part of a screw is held rotatably, and the spline outer cylinder spline-bonded to the screw spline shaft is fitted to a vehicle moving forward/backward integrally with the screw.
