PROBLEM TO BE SOLVED: To provide the injection device of an injection molder, in which an impact noise can be suppressed smaller and, at the same time, the injection device can be surely prevented from being damaged by a method wherein the impact between a travelling unit and a fixed member can be smoothly absorbed when the travelling unit reaches its advancing limit without stopping the travbelling unit at its predetermined position. SOLUTION: By means of coned disc springs 27 provided between a screw holding member 3 and a heating cylinder holding member 2 the impact of the collision developing between a travelling unit and the heating cylinder holding member 2 at the stopping of the travelling unit at its advancing limit is smoothly absorbed so as to check the generation of an impact noise and, at the same time, surely prevent the injection device from being damaged.
