PROBLEM TO BE SOLVED: To prevent the deterioration of the operation feeling of a brake pedal. SOLUTION: The braking device of a vehicle in which a motor 30 for generating wheel driving force or regenerative wheel braking force is arranged is provided with: a machine vehicle braking force generation means equipped with a working fluid pressure adjusting part (brake actuator 67) for generating a machine vehicle braking force by transmitting the pressure of working fluid generated when an operation pressure to a brake pedal 63 by a driver is transmitted to respective wheels 10FR, 10FL, 10RR and 10RL as it is or by increasing or decreasing it; an external braking force generation means (traveling resistance generation means 90) for applying any external braking force other than the regenerative wheel braking force by the motor 30 and the machine vehicle braking force by the machine vehicle braking force generation means to the vehicle; and a braking control means (integrated ECU 70, traveling resistance variable ECU 91) for, when conversion efficiency into the electric energy of the motor 30 decreases, covering braking force equivalent to the decrease portion of conversion efficiency with the external braking force so that the request vehicle braking force of the driver can be fulfilled.
