とを特徴とする負圧The inside of the casing is defined by a diaphragm and a power piston coupled to the diaphragm into a vacuum chamber that communicates with a negative pressure source and an atmospheric chamber that can selectively communicate with the atmosphere via a negative pressure source or an air intake port. The communication between the negative pressure source and the atmospheric chamber is cut off by the operation of the input rod facing the vacuum chamber, and the atmospheric chamber is opened to the atmosphere, and the power piston is operated by the pressure difference between the vacuum chamber and the atmospheric chamber to generate the power In a negative pressure booster that operates a master cylinder via an output rod attached to a piston and transmits reaction force from the master cylinder to an input rod via a reaction rubber, the device is integrated with the power piston. A negative pressure characterized in that a retaining plate having a hollow cylindrical guide portion in the axial direction is provided on the formed shaft core portion, and the shaft portion of the output rond is guided by the guide portion of the plate.
