An electric motor is controlled according to an operation of a brake pedal connected to an input rod to drive a ball-screw mechanism through a transmission mechanism, thereby propelling a primary piston and a subpiston to generate brake hydraulic pressure in a master cylinder. The brake hydraulic pressure in the master cylinder is received with an input piston and transmitted to the brake pedal through a plunger rod and the input rod. The input rod and the plunger rod are tiltably connected, through a ball joint, and the plunger rod is axially slidably guided by a guide part of a rear cover. Thus, a lateral force acting on the primary piston or the subpiston is reduced to prevent an increase in sliding resistance and degradation of sealing performance.

An electronic control unit inputs a side slip angle β of a vehicle body in step S11. Next, in step S13, the unit calculates, while using the side slip angle β of the vehicle body, a dynamic zero point δo for reducing a lateral force generated in the vehicle due to the side slip angle β of the vehicle body. Next, in step S14, the unit calculates a steering angle δa, which is represented by the difference between the dynamic zero point δo and a steering angle δ detected by a steering angle sensor. Next, in step S15, the unit calculates a reaction torque Tz having a predetermined relation with the steering angle δa. Subsequently, in step S16, the unit drives and controls an electric motor to generate the calculated reaction torque Tz. Thus, the unit guides a driver to a proper steering-wheel rotating direction.
