An electric brake system (34) mounted in a vehicle includes a rotating body, a friction member (126), an electric motor (18), pistons (42a, 86, 142) and a motion converting mechanism (150), and is equipped with an actuator (110) and a controller. The motion converting mechanism (150) includes a rotating member and a linear motion member. The controller is configured to selectively perform (a) a standby control for making the linear motion member stand by in a standby position where a clearance between the friction member (126) and the rotating body is not greater than a backlash between male and female screws, or (b) a retreat control for making the linear motion member retreat to a retreat position that allows the clearance to be equal to or greater than the backlash when there is no demand for a braking force for the electric braking device (34).

    차량에 장비되는 전동 브레이크 장치(34)는, 회전체와 마찰 부재(126)와 전동 모터(18)와 피스톤(42a; 86; 142)과 동작 변환 기구(150)를 갖고, 액추에이터(110)와 컨트롤러를 구비한다. 동작 변환 기구(150)는 회전 부재와 직동 부재를 포함하여 구성된다. 컨트롤러는, 전동 브레이크 장치(34)에 대한 제동력 요구가 없는 경우에, (a) 마찰 부재(126)와 회전체의 클리어런스가 수나사와 암나사의 백래시보다 크게 되지 않는 대기 위치에, 직동 부재를 대기시키는 대기 제어와, (b) 클리어런스가 백래시 이상이 되는 것을 허용하는 후퇴 위치로, 직동 부재를 후퇴시키는 후퇴 제어를, 선택적으로 실행하도록 구성되어 있다.
