Abstract
Disclosed is an electric actuator capable of effectively absorbing shock exerted on its component part. The electric actuator has a housing, a rod cover, a piston, a feed screw, a sliding nut, two piston dampers for absorbing shock exerted on the piston, a first end damper attached to one of the opposite ends of the housing, a second end damper attached to the rod cover. The sliding nut is axially displaceable relative to the piston when the piston damper absorbs shock.
