Abstract

An electric actuator has a housing with an electric motor mounted on the housing (). A ball screw mechanism converts rotational motion of the electric motor to an axial linear motion of a drive shaft. A side-cover () is detachably mounted to the housing (). A guide member () is mounted on the inner wall of the side-cover (). The guide member () has a substantially 'C'-shaped cross-section and includes a recessed groove () axially extending opposite to the drive shaft (). A rotation-preventing pin (), mounted on the outer circumference of the threaded screw shaft (), engages with the guide member () to support the threaded screw shaft () so that it can be axially moved relative to the housing () but cannot be rotated.
