PROBLEM TO BE SOLVED: To facilitate alignment between an injection heating cylinder and a screw driving body by a simple means over after assembling by installing a means for adjusting the height of the screw driving means in a motor-operated injection mechanism. SOLUTION: A front plate 1 having the injection heating cylinder 4 fitted with a screw 3 in the middle of the front part, and a rear plate 2 having an injection driving electric motor 5, are mounted/fixed onto an installation member 7. The front and rear plates 1 and 2 are connected by a plurality of guide bars 6 installed right and left between the plates. The screw driving body 10 is inserted into the guide bars 6 and installed to move freely forward/backward between the plates. A driving means by a ball screw shaft 11 and a ball nut member 12 which is connected to the motor 5 is installed across the screw driving body 10 and the rear plate 2. On both sides of the lower part of the screw driving body 10 between it and the installation member 7, the screw driving body 10 is supported freely slidably, and an alignment member 16 having a height adjusting means 16 is installed.
