Abstract
An electric booster is provided having a force-feedback-control structure. The electric booster includes a master piston having a nut unit rectilinearly moved in a booting cylinder space by receiving driving power generated by a motor and a hydraulic pressure generated by a pedal effort. A first screw has a first end connected to the motor and a second end extending into the boosting cylinder, and is rotated by the motor operating with the brake pedal. A second screw is disposed to face the first screw to have a separation space. A connecting member connects the first screw and the second screw. A pressure balancing member has contact surfaces in contact with the second end of the first screw and the connecting member, respectively, and is deformed by a difference between two pressures when applied to the contact surfaces in a longitudinal direction of the first screw, respectively.
