Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an electric vehicle brake operating device capable of certainly performing re-adhesion by high speed control only by electric braking force without invalidating an electric brake even when adhesion coefficient is largely lowered in such a state that air braking force is not supplemented exceeding supplementary air braking force at skid detection or at skid recognition. SOLUTION: A skid detection signal is inputted from an electric vehicle control device to the electric vehicle brake operating device and the skid detection can be performed in the electric vehicle brake operating device or the electric vehicle brake operating device can recognize the skid from the change circumstance of a regeneration brake force feedback signal inputted to the electric vehicle brake operating device. When the electric vehicle brake operating device detects or recognizes the skid, it is suppressed that air braking force instruction is increased exceeding an air braking force instruction value at the detection/recognition of the skid by a predetermined period on or after the detection/recognition of the skid. Thereby, it is avoided that the electric braking force is gradually lowered by repeating skid re-adhesion control, and generation of a phenomenon that the electric braking force is invalidated is eliminated.
