式射出装置。[Scope of Claim for Utility Model Registration] In an electric injection device configured to move a screw back and forth by converting the rotational motion of an electric motor into linear motion, the piston of a fluid pressure cylinder moves back and forth together with the screw. The chamber on the side where the volume increases when the screw of the hydraulic cylinder moves forward is always open, and the chamber on the side where the volume decreases when the screw of the hydraulic cylinder moves forward is opened to the working fluid via the flow restriction device. An electric injection device characterized in that a switching valve is capable of switching between a state in which working fluid is released without going through a flow restriction device, and a state in which working fluid is released without going through a flow restriction device.
