Abstract: PROBLEM TO BE SOLVED: To provide an electric linear actuator of which the position can be securely held at the stop of an electric motor. SOLUTION: A ball screw actuator is provided with an actuator body 10 with a ball screw 1 for converting rotation into linear motion, the electric motor 20 and a gear mechanism 30 for transmitting the rotation of the electric motor 20 to the actuator body 10. Since the actuator has one holding mechanism 40 engaged with a gear 31 constituting the gear mechanism 30 to hold the position of the actuator body 10, the rotation of the gear 31 is inhibited so as to securely hold the position of the actuator body 10. In particular, this configuration to inhibit the rotation of the gear by engagement with teeth of the gear eliminates the possibility of the slip of the engagement face such as friction engagement, and the position can be stably held even if a vibration load is applied.
