PROBLEM TO BE SOLVED: To provide an electric actuator simply constructed to actualize smooth axial movement of a shift select shaft.SOLUTION: A shift conversion mechanism 11 includes a screw shaft 29 (a supporting shaft) to be rotationally driven by an electric motor, and a ball nut 30 (a movable body) to be moved in a second axial direction X2 of the screw shaft 29. A connection mechanism 52 for connecting a connection arm 32 connected to the ball nut 30 to a shift select shaft 3 includes a connection groove 63 inserted through the shift select shaft 3 in a first radial direction R1 and extending in a first axial direction X1 of the shift select shaft 3, and a connection pin 64 fixed to a second connection part 53 of the connection arm 32 via a bush 60. The connection groove 63 has a first inner wall 67 and a second inner wall 68 opposing each other in a second radial direction R2 perpendicular to the first radial direction R1. A space between the first inner wall 67 and the second inner wall 68 is larger than the diameter of the connection pin 64. |
