PROBLEM TO BE SOLVED: To prevent the falling of a fixed platen by nozzle touching force. SOLUTION: A concave recess part 10 is formed in the injection axis direction in a base frame 1. Collars 2a are formed on both sides of the fixed platen 2. The bottom surface of the fixed platen 2 is fixed to the recess part 10, and the lower surfaces of the collars 2a are fixed to the upper surface of a recess 10 side part. The nozzle touching force applied from a nozzle attached to the tip of a screw cylinder 6 is applied to an approximately central part of the fixed platen 2. Since the distance in the height direction between the lower surfaces of the collars 2a when the fixed platen 2 is fixed to the base frame 1 and a height position to which the nozzle touching force is applied is shortened as compared with the distance when the fixed platen 2 is not fixed by using the collars 2a, the moment to tumble the fixed platen 2 which acts by the nozzle touching force is decreased, preventing the falling of the fixed platen 2.
