Abstract

Provided is an electric braking device that transmits power generated by an electric motor MTR to a pressing member PSN and causes pressing force to be generated by the pressing member PSN with respect to a friction member MSB. Hysteresis characteristics in the relation between the power supply amount to the electric motor and the pressing force of the pressing member are detected each time a predetermined point in time arrives. Upon determination of a 'holding state in which the pressing force is held constant', a minimum value for a power supply amount that makes it possible to maintain the current pressing force is obtained on the basis of the most recently detected hysteresis characteristics and the power supply amount is set to a value determined on the basis of the obtained minimum value for the power supply amount.
