Abstract
Provided is an electric actuator, including: a driving motor (2); a motion conversion mechanism (6) configured to convert a rotary motion of the driving motor (2) to a linear motion in an axial direction parallel with an output shaft (2a) of the driving motor (2); and a transmission gear mechanism (5) configured to transmit a driving force from the driving motor (2) to the motion conversion mechanism (6). The driving motor (2) is mounted to an actuator case (9) to which a double-row bearing (24) configured to support the motion conversion mechanism (6) and a bearing (19) configured to support the transmission gear mechanism (5) are mounted.
