In the electric actuator, the worm 6 is loosely fitted to the rotating shaft 5 such that the worm 6 is movable within a predetermined range in the axial direction of the rotating shaft 5, and the worm 6 is movable in the rotational direction of the rotating shaft 5. Engagement means 11, 1 that engages with
6 is formed on the worm 6 and the rotating shaft 5.
