Disclosed is an actuator for an electric brake. According to one embodiment of the present disclosure, provided is the actuator for an electric brake, which comprises: a motor shaft where screw threads are formed on an outer circumferential surface; a nut screw-coupled to the motor shaft; a guide member coupled to an outer circumferential surface of the nut to be moved with the nut; a screw guide guiding the guide member to be linearly moved according to rotation of the motor shaft; and a piston coupled to the nut to be linearly moved with the nut. Rotation of the piston is retrained by the guide member.

    전동식 브레이크의 액추에이터를 개시한다. 본 개시의 일 실시예에 의하면, 외주면에 나사산이 형성되는 모터샤프트(motor shaft); 모터샤프트와 나사결합되는 너트(nut); 너트의 외주면에 결합되어 너트와 함께 이동하도록 구성되는 가이드부재(guide member); 모터샤프트가 회전함에 따라 가이드부재가 직선운동하도록 안내하는 스크류 가이드(screw guide); 너트에 결합하여 너트와 함께 직선운동하도록 구성되는 피스톤(piston)을 포함하되, 가이드부재에 의하여 피스톤의 회전이 구속되는, 전동식 브레이크의 액추에이터를 제공한다.
