Claims

[Claims for Utility Model Registration] (1) Cantilevered in a valve positioner that is attached to the yoke of a control valve and in which a feedback lever is connected to the valve stem by a pin that engages with a long hole in the lever. A connecting structure for a valve positioner, characterized in that a linear spring is selectively disposed at each end of the elongated hole, and the spring presses the pin against one edge of the elongated hole. (2) A utility model according to claim 1, characterized in that a bent piece is integrally formed on one side edge of the elongated hole so as to be bent almost orthogonally to the feedback lever. Valve positioner connection structure.
