<P>PROBLEM TO BE SOLVED: To suppress fluctuation of brake manipulated variable due to consumed fluid amount fluctuation and fluid pressure fluctuation of a brake circuit by simple structure to advantageously realize a desired stroke characteristic of a brake operation means, in a brake fluid pressure generating device having a boosting means. <P>SOLUTION: This device is provided with a negative pressure type boosting device 21 having an input shaft 28 operated by a brake operation, a stroke simulator 29 for imparting stroke and reaction according to the brake manipulated variable to the input shaft 28 and a control valve 37, a master cylinder 22 for generating brake fluid pressure, and a pressure detecting member 23 for detecting fluid pressure of a pressure chamber 22b to apply reaction according to the detected fluid pressure to a valve member 40 of the control valve 37. An input transmitted via the stroke simulator 29 and the reaction from the pressure detecting member 23 are opposed and received by the control valve 37 to balance the reaction in relation to the input. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
