PROBLEM TO BE SOLVED: To improve the operational feeling in quick braking operation of a brake fluid pressure generating device which outputs the fluid pressure supplied from a fluid pressure source after regulating the same to a value corresponding to the brake operating force by a regulator of which an operating state is changed in accordance with the displacement of an input piston and a simulator piston. SOLUTION: A simulator chamber CS in the input piston 43 faced to the simulator piston 44 is connected to an atmospheric pressure reservoir 3 through an orifice 7, and the overflow of the brake fluid from the simulator chamber CS is restricted by the orifice 7 in the quick braking operation to delay the stroke of a brake pedal 6.
