PROBLEM TO BE SOLVED: To correctly measure injection pressure and back pressure from the quantity of distortion of a steel sheet even when an apparatus is miniaturized by adopting a lengthy steel sheet for connecting the front and rear plates of an electric injection unit and making the steel sheet a distortion member for detecting pressure. SOLUTION: An injection plate holding the rear end of a screw in an injection heating cylinder rotatably is set forward/backward movably between the front plate having the injection heating cylinder and the rear plate having an electric motor for injecting/driving. The plates are fixed to the sliding stand of a guide means placed on the upper surface of a base to be set movably on the base. The front and rear plates are separated from the injection plate and connected to each other by lengthy steel sheets set on both sides of the plate. At least one of the steel sheets is fitted with a distortion detector on the side to be the distortion member for detecting pressure. COPYRIGHT: (C)2008,JPO&INPIT
