The electric actuator includes an electric motor and a reduction gear, an eccentric rotary part is disposed in an output shaft of the electric motor, and the eccentric rotary part becomes an input shaft part of the reduction gear. In the reduction gear, the rotation of the eccentric rotary part is reduced to output, and in the electric motor, pulsation is generated in output torque. Therefore, in the actuator control device, supply current to the electric motor is controlled on the basis of a value obtained by subtracting an actual value from a design value of the torque in an operation state of an electric brake. With this, it is possible to suppress pulsation of the torque and suppress irregularity of responsiveness caused by pulsation.SELECTED DRAWING: Figure 5
