Abstract:
An actuator includes a rod, an electric motor to generate a rotational driving force on supply of electricity, an output shaft to output the rotational driving force of the electric motor to the rod, a feed screw mechanism, and a rotation prevention mechanism. The feed screw mechanism includes a female screw portion formed on one of the output shaft and the rod, and a male screw portion formed on the other to mesh with the female screw portion. The rotation prevention mechanism is configured to regulate rotation of the rod caused by the rotational driving force of the electric motor.
