Claims

[Scope of utility model registration request]

In an actuator, the base end of an operating rod is fixed to a rotation-preventing nut that is threaded onto a screw shaft rotationally driven by an electric motor and moves linearly, and an overload prevention means is provided at the base end of the screw shaft. , a tip metal fitting having an outer periphery with a threaded groove is fixed to the front end of the actuating rod, a retreating end setting adjustment cylinder having a locking means is screwed into the thread groove of the tip metal fitting, and the outer cylinder of the actuator is fixed. Attach a fixing nut with a threaded groove on the inner circumference to the tip,
A stroke end adjustment device for a linear actuator, in which a forward end setting adjustment cylinder having a locking means is screwed into the inner peripheral thread groove of the fixing nut.
