Abstract
An electric actuator 1 includes: an electric motor 10; a first motion conversion mechanism 20 that has a screw shaft 21 rotatably driven by the electric motor 10 and a nut 22 screwed with the screw shaft 21, and converts a rotary motion of the screw shaft 21 into a linear motion of the nut 22; and a housing 40 accommodating the electric motor 10 and the motion conversion mechanism 20. The housing 40 includes a pair of housing split bodies 41 and 42 split by a plane parallel to an axial direction of the screw shaft 21.
Claims6
