A ball screw attached to a lower portion of a fixed platen is rotated, thereby moving a nut member forward and moving an injection device forward through a spring. By moving the injection device forward, a nozzle on a tip end of a screw cylinder is abutted against the fixed platen, and a nozzle touch force is applied to the fixed platen by a compressive force of the spring. A connection member is provided between an upper portion of the fixed platen and a front plate of the injection device so as to be able to connect or disconnect the fixed platen to or from the front plate. Even if the nozzle touch force acts on the fixed platen, the fixed platen is supported by the upper portion and the lower portion of the fixed platen and is prevented from falling down. |
