PURPOSE: A clutch device for an electric valve actuator is provided to reduce a failure rate by simplifying the separation structure of the motor shaft of a main motor and the handle shaft of a manual handle. CONSTITUTION: A clutch device(1) for an electric valve actuator comprises a drive gear(10), a clutch disc(20), an elastic member(30), a driven gear(40), a stopper(50), and a turning force supply unit(60). The clutch disc is inserted into a handle shaft through a coupling hole(22). The elastic member is inserted between one side of a manual handle(120) and the clutch disc. The driven gear is meshed with the drive gear and is rotated with the drive gear when the handle shaft is rotated. The stopper has a rotary body and a support rib. The turning force supply unit is connected to the stopper and supplies turning force to the stopper. |
