。 It is equipped with a pair of counter gear trains that convert changes 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 the set limit positions determined at both ends of the stroke. and a three-point indicator attached to a valve actuator configured to intermittently operate the intermittent output shaft of one of the corresponding counter gear trains to switch one of the pair of limit switches. cam elements mounted on mutually opposing positions of both of the intermittent output shafts, and a first tilting element located between these two cam elements and tilted about a first fulcrum by being biased by the cam element. a second tilting member that is operatively connected to the tilting member and tilts about a second fulcrum set at a position where the tilting member can amplify the tilting member; and elasticity that urges the tilting member to a neutral position. The pointer is configured to allow the pointer to perform a three-point pointing operation by the selective operation of the cam element and the three-step movement of the second tilting member induced by the elastic member. Three-point indicator for valve actuator.
