Zusammenfassung:	To improve responsiveness of an electric linear actuator.According to an embodiment of the present invention, there is provided an electric linear actuator including an outer cylinder, an electric motor attached to the outer cylinder, a ball screw configured to convert rotational motion output by the electric motor into linear motion in a predetermined direction, and a ball spline configured to transmit only the linear motion in the predetermined direction. The ball screw includes a screw shaft coupled to a shaft of the electric motor, and a first nut attached to the outer cylinder and fitted to the screw shaft. The ball spline includes a spline shaft connected to the first nut, and a second nut attached to the outer cylinder and fitted to the spline shaft.
