シヨナ。[Claims for Utility Model Registration] In a positioner that converts the displacement of a magnetic unit into an output of a pilot relay via a nozzle flapper mechanism, a flat part is provided between the tip of the operating shaft of the magnetic unit and one end of the flapper beam of the nozzle flapper mechanism. A ball having a section is interposed therebetween, a spherical section of the ball is slidably fitted into a spherical seat recessed in the actuating shaft, a flat section is brought into close contact with the flapper beam, and the flapper beam is connected to the flapper beam by an elastic member. A positioner characterized by being slidably pressed against a flat part.
