Abstract
Provided is an electric actuator, including: a drive part (2); a motion conversion mechanism part (3) configured to convert a rotary motion from the drive part (2) into a linear motion in an axial direction in parallel to an output shaft of the drive part (2); and a lock mechanism part (7) configured to prevent drive by the motion conversion mechanism part (3). The lock mechanism part (7) includes: a rotary motor (64); and a lock member (60), which is driven by the rotary motor (64) so as to be brought into at least any one of a locking state of preventing the drive by the motion conversion mechanism part (3) and an unlocking state of releasing the locking state.
