To provide an electric actuator that can be easily replaced even when it is desired to replace the electric actuator independently of an output target of rotational force.SOLUTION: An electric actuator 100 includes: an output shaft 1 for outputting rotational force to an output target; an electric motor 2 for rotationally driving the output shaft 1; a controller 3 for controlling the electric motor 2; a speed reduction mechanism 4 disposed between the output shaft 1 and the motor 2; an irreversible mechanism 5 that is disposed between the output shaft 1 and the electric motor 2 to prevent back drive torque from being transmitted from an output side to an input side; a position sensor 6 for detecting a rotation position of the output shaft 1; and a housing 7 in which the output shaft 1, the electric motor 2, the controller 3, the speed reduction mechanism 4, the irreversible mechanism 5 and the position sensor 6 are disposed, and which can be attached to and detached from an installation target independently of the output target.SELECTED DRAWING: Figure 1

    【課題】回転力の出力対象とは独立して電動アクチュエータを交換したい場合にも、容易に交換することが可能な電動アクチュエータを提供する。【解決手段】この電動アクチュエータ100は、出力対象に回転力を出力する出力軸1と、出力軸1を回転駆動させる電動モータ2と、電動モータ2を制御するコントローラ3と、出力軸1と電動モータ2との間に配置された減速機構4と、出力軸1と電動モータ2との間に配置され、出力側からのバックドライブトルクを入力側に伝達することを阻む非可逆機構5と、出力軸1の回転位置を検知する位置センサ6と、出力軸1、電動モータ2、コントローラ3、減速機構4、非可逆機構5、および、位置センサ6が配置され、出力対象とは独立して取付対象に着脱可能な筐体7と、を備える。【選択図】図1
