• an actuator that provides power;
• a rotator rotated by the actuator;
• a nut that rotates together with the rotator and is provided to be slidably movable with respect to the rotator and that has a second screw thread formed on an inner circumferential surface thereof to mesh with the first screw thread;
• and
• a housing having an accommodation space at an inside thereof;
• wherein the housing includes:
• a panel fixed to a dash panel and having a rear side on which a master cylinder is disposed;
• and
• a cover that forms the accommodation space and extends toward the brake pedal, to be coupled to a front side of the panel, and
• wherein the first anti-rotator includes:
• an anti-rotation body provided in a cylindrical shape and provided to pass through a through hole that passes through the cover,
• at least one anti-rotation protrusion provided on an outer circumferential surface of the anti-rotation body, and
