Abstract
An input pressure detecting device is arranged in an input side of a pneumatic brake booster, which comprises an elastic member having a given portion which expands when a pressure is applied to the elastic member, a pressure sensor for issuing, upon receiving a pressure, a signal representative of the intensity of the pressure applied thereto, and an axially movable piston intimately disposed between the given portion of the elastic member and the pressure sensor. Upon application of force to the elastic member due to depression of the brake pedal, the elastic member is compressed causing the given portion to expand and thus applying a corresponding but small pressure to the pressure sensor through the piston.
