ABSTRACT:
A negative pressure type booster 1 includes a housing 2, a movable wall 3 which divides the interior portion of the housing 2 into a constant pressure chamber 4 and a variable pressure chamber 5, a power piston 6 which outputs a brake output toward an output rod 10, an input member 8 which can be moved by a brake actuation, and a control valve 13. The output rod 10 can be divided into a first output rod 101 and a second output rod 102. The output rod 10 includes an auxiliary movable wall 17 which is provided within the constant pressure chamber 4 in such a manner that it can be moved by a given amount and also which can be engaged with the second output rod 102, a diaphragm 18 which is engaged with the auxiliary movable wall 17 in order to form an auxiliary variable pressure chamber 19 between the auxiliary movable wall 17 and itself, and communication chamber switching device which allows the auxiliary variable pressure chamber 19 to communicate selectively with either the constant pressure chamber 4 or the atmosphere.
