To provide an electric actuator having improved operation stability and durability of a lock mechanism.SOLUTION: The electric actuator includes: a drive motor 7; a motion conversion mechanism 5 for converting a rotational motion of the drive motor 7 into a linear motion; a transmission gear 14 for transmitting the rotational motion of the drive motor 7 to the motion conversion mechanism 5; and a lock mechanism 6 for preventing operation of the electric actuator by reverse input from the motion conversion mechanism 5 to the drive motor 7. The lock mechanism 6 includes friction members 34, 35 which are relatively close to the transmission gear 14 and hold the transmission gear 14 from both sides in the axial direction.SELECTED DRAWING: Figure 1

    【課題】ロック機構の作動安定性及び耐久性を向上させた電動アクチュエータを提供する。【解決手段】駆動用モータ7と、駆動用モータ7の回転運動を直線運動に変換する運動変換機構5と、駆動用モータ7の回転運動を運動変換機構5に伝達する伝達ギヤ14と、運動変換機構5側から駆動用モータ7側への逆入力による電動アクチュエータの作動を防止するロック機構6とを備える電動アクチュエータにおいて、ロック機構6は、伝達ギヤ14に対して相対的に接近して伝達ギヤ14を軸方向の両側から挟んで保持する摩擦部材34,35を備える。【選択図】図1
