Claims

[Scope of utility model registration request]

A counter gear train is provided that converts a change in the operating position of the output shaft of the valve actuator body into a counting operation, and when the output shaft reaches one of set limit positions determined at both ends of the stroke, A three-point indicator attached to a pulse actuator configured to intermittently operate the intermittent output of one of the corresponding counter gear columns so that either of the pair of limit switches can switch one of the pair of limit switches, , comprising cam elements respectively mounted on mutually opposing positions of both the intermittent rotation shafts, a tilting plate bridging these both cam elements, and an elastic member bringing the tilting plate into elastic contact with both the cam elements. A three-point indicator for an actuator, characterized in that the pointer is configured to perform a three-point indicating operation by three-stage movement of the tilting plate caused by the selective operation of the cam element.
