PROBLEM TO BE SOLVED: To provide an injection device of a molding machine in which influence of moment caused by arrangement of a driving device in parallel with a plunger can be reduced.SOLUTION: An injection device 1 includes a plunger 5, an injection cylinder device 7 connected in series to the plunger 5, a driving device 11 arranged in parallel with the injection cylinder device 7, and a balance cylinder device 12 which is arranged on the opposite side from the driving device 11 with respect to the injection cylinder device 7 in parallel with the injection cylinder device 7. A balance cylinder tube 57 of the balance cylinder device 12 is driven in a movement direction of an injection piston rod 21, and restrained from moving forward relatively to the injection piston rod 21 and allowed to move back relatively to the injection piston rod 21. |
