Abstract
An electric actuator includes a motor, a speed reduction mechanism, a first bearing, and a bearing holder. The speed reduction mechanism has external and internal gears, an output flange that is positioned at one side in an axial direction from the external gear, and a plurality of projecting portions that project in the axial direction from one of the output flange and the external gear toward the other. The plurality of projecting portions are inserted into a plurality of first bore portions disposed along a circumferential direction, respectively. The bearing holder has a cylindrical circumferential wall positioned at an outer side in a radial direction of the first bearing and a support wall supporting the first bearing from the other side in the axial direction. A position adjustment mechanism configured to be capable of moving the support wall in the axial direction is arranged in the bearing holder.
