Title: ELECTRIC FLOW CONTROL VALVE AND ACTUATOR
Abstract:
An actuator (70) comprises a rod (71), an electric motor (72) that can generate a rotational driving force with a current, an output shaft (73) that outputs the rotational driving force of the electric motor to the rod, a feed screw mechanism (70a, 70b), and a rotation prevention mechanism (75). The feed screw mechanism comprises a female threaded portion (731a to 731c) that is provided on one member of the output shaft and the rod, and a male threaded portion (711a, 716a, 718a) that is provided on the other member and that meshes with the female threaded portion. The rotation prevention mechanism is configured so that the rotation of the rod is regulated by the rotational driving force of the electric motor.
