A vehicle braking device including a braking operation judging unit that judges that a braking operation is input when a fluid pressure detected by a pressure detecting sensor is not smaller than a threshold value set in advance in a process of a first mode in which it is judged that the device normally operates, and judges that the braking operation is input when judging that wheel deceleration of a tire detected by a wheel speed detecting sensor is larger than a threshold value in a process of a second mode in which it is judged the pressure detecting sensor does not normally detect a pressure or it is judged that a failure occurs in the fluid pressure, and a control unit puts a brake lamp arranged on a vehicle body into a lighting state from a non-lighting state when it is judged that the braking operation is input.
