Abstract

Provided is an electric actuator (), including: a motor part (A); and a motion conversion mechanism part (B) configured to convert a rotary motion of the motor part (A) into a linear motion to output the linear motion. The motion conversion mechanism part (B) includes: a screw shaft () arranged coaxially with a rotation center of a rotor () of the motor part (A); and a nut member () rotatably fitted to an outer periphery of the screw shaft. The rotor () includes a rotor inner () serving as a hollow rotary shaft having the nut member () arranged on an inner periphery thereof. A rotary motion of the rotor () is transmitted to the nut member () through an intermediate member (Z) arranged between an inner peripheral surface of the rotor inner () and an outer peripheral surface () of the nut member ().
