To provide an electric actuator and an actuator device capable of improving accuracy in displacing an object.SOLUTION: An electric actuator in one embodiment, includes a motor portion, a decelerator portion, a control portion, a first rotation sensor capable of detecting rotation of the motor portion, and a second rotation sensor capable of detecting rotation of an output shaft connected to the decelerator portion. The control portion executes first rotation angle acquisition control for acquiring a target rotation angle of the output shaft in moving a movable portion from a second position to a first position, as a first rotation angle. The first rotation angle is a rotation angle of the output shaft at a second position side with respect to abutting of the movable portion on a first wall portion. The control portion makes the movable portion abut on the first wall portion by rotating the output shaft in the first rotation angle acquisition control, acquires the rotation angle of the output shaft when the movable portion abuts on the first wall portion, on the basis of a result of detection by a second rotation sensor, and calculates the first rotation angle on the basis of the rotation angle of the acquired output shaft.SELECTED DRAWING: Figure 5

    【課題】対象物を変位させる精度を向上できる電動アクチュエータ、およびアクチュエータ装置を提供する。【解決手段】本発明の電動アクチュエータの一つの態様は、モータ部と、減速機部と、制御部と、モータ部の回転を検出可能な第1回転センサと、減速機部に接続される出力シャフトの回転を検出可能な第2回転センサと、を備える。制御部は、第2位置から第1位置に可動部を移動させる際における出力シャフトの目標回転角度を、第1回転角度として取得する第1回転角度取得制御を行う。第1回転角度は、可動部が第1壁部に突き当たるよりも第2位置側となる出力シャフトの回転角度である。第1回転角度取得制御において制御部は、出力シャフトを回転させて可動部を第1壁部に突き当て、可動部を第1壁部に突き当てた際の出力シャフトの回転角度を第2回転センサの検出結果に基づいて取得し、取得した出力シャフトの回転角度に基づいて第1回転角度を算出する。【選択図】図5
