Zusammenfassung:PURPOSE:To adjust a brake feeling arbitrarily, easily and stably by easily changing jumping in a simple constitution. CONSTITUTION:In the half built-up state of a negative pressure boost device, a measuring means 17 for detecting the axial displacement is provided on a negative pressure constant pressure chamber ra1. When the interior of the negative pressure constant pressure chamber ra1 is put in the negative pressure state and an input rod 11 is displaced above a specified amount, detection is conducted by the measuring means 17 to perceive the inhibit position of a valve plunger 9, and the distance from the perceived position to the positions of the valve plunger 9 and a reaction disc is taken as a gap (d) for jumping characteristic.
