An electric automobile braking device can mitigate the motion frequency of a hydraulic booster device of a master cylinder with no vacuum booster that assists the electric automobile, and can inhibitthe braking sense decline to the minimum level. The electric automobile braking device includes the master cylinder that has no vacuum booster and the hydraulic booster device that can increase a brake fluid pressure generated by the master cylinder. Switching is possible between a normal braking mode in which hydraulic braking and regenerative braking are used in combination when a percentage charge of a battery is less than a threshold value and a regenerative braking restriction mode in which hydraulic braking is permitted and regenerative braking is restricted when the battery charging percentage reaches a threshold value or greater. In the regenerative braking restriction mode, when a depressing force of a brake pedal by a driver exceeds a first depressing force over a predetermined period of time, an operation of the hydraulic booster device is suppressed, thus preventing the braking sense decline caused by excessive motions of the hydraulic booster device, the formation of motion sounds by the hydraulic booster device, and the power consumption increase of the hydraulic booster device.
