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 a transmission gear mechanism (28) configured to transmit a driving force from the drive part (2) to the motion conversion mechanism part (3); and a lock mechanism part (7) configured to prevent the drive by the motion conversion mechanism part (3), wherein the transmission gear mechanism (28) includes a first gear (30) arranged on the drive part (2) side and a second gear (31) arranged on the motion conversion mechanism part (3) side, and wherein the lock mechanism part (7) is arranged on an opposite side of the drive part (2) with respect to the first gear (30), and on the motion conversion mechanism part (3) side with respect to a rotation center line of the first gear (30).
