PROBLEM TO BE SOLVED: To provide a lightweight electromotive injection device having long life and being shortened in the total length. SOLUTION: The electromotive injection device has a heating cylinder 1 in which a screw 2 is housed in a rotatable manner and also has a fixed plate 4 to which the end part of the heating cylinder 1 is attached, the end plate 6 arranged in opposed relation to the fixed plate 4 and the movable plate 5 arranged between the fixed plate 4 and the end plate 6 on a unit stand 9 in a slidable manner and is constituted so that the screw 2 is advanced by the movable plate 5 to inject the molten resin in the heating cylinder 1. This electromotive injection device has a guide bar 7 for connecting the fixed plate 4 and the end plate 6 and the linear guide bearing 8 provided on the unit stand 9 in the axial direction of the screw 2 in a slidable manner and the movable plate 5 is slid while guided by the guide bar 7 and the linear guide bearing 8.
