A residual pressure removal device of an ejector is provided to prevent the waste of materials by discharging paste-state materials such as silicon, etc. in the appropriate amount and maintaining internal pressure when unnecessary not to be discharged continuously. A residual pressure removal device of an ejector includes a piston hook(20) having an insertion hole(21) to insert a hanging projection(13) and an inside space(22), a piston pusher(30) having a bolt hole(33) to be fastened to the end of an interlocking rod(40), and an interlocking device(90) operating the piston pusher rightward and leftward, wherein the piston hook pushes a piston(11) to increase the internal pressure of a syringe(10) and to discharge the materials by operating the interlocking rod, and the piston hook pulls the piston to decrease the internal pressure of the syringe and to stop the discharge of the materials. |
