Abstract
An electric actuator includes a motor including a rotor having a motor shaft extending along a central axis and a stator, a deceleration mechanism connected to the motor shaft, an output shaft, a first bearing, a second bearing, and a deceleration mechanism case. The first bearing is fitted on an eccentric axis part of the motor shaft. The deceleration mechanism includes an internal gear in a ring shape, an external gear connected to the eccentric axis part, and an output flange part which transmits rotation of the external gear around the central axis to the output shaft. The deceleration mechanism case includes a case body and a cup member. The cup member includes a first cylinder part to which the internal gear is fitted on the radial-direction inner side, and a second cylinder part to which the second bearing is fitted on the radial-direction inner side.
