。 −[Claims for Utility Model Registration] A power piston slidably disposed within a shell, a valve mechanism housed within a valve body of the power piston shaft, and a constant pressure formed on the front side of the power piston in the operating direction. A variable pressure chamber formed on the rear side of the chamber, an input shaft that operates the valve mechanism to switch the flow path and supply positive pressure to the variable pressure chamber to move the power piston to the front, and the variable pressure chamber and the constant pressure chamber. In a positive pressure brake booster equipped with a relief valve that releases the pressure to a constant pressure chamber when the pressure difference exceeds a predetermined value, the valve body is connected to at least one side of the constant pressure chamber and one side of the variable pressure chamber. A direction in which the variable pressure chamber side member forms a valve seat on which the valve body of the IJ-F valve is seated, and between the constant pressure chamber side member and the valve body of the relief valve, the two are separated. An engaging portion formed on the valve body is engaged with the member on the constant pressure chamber side with a spring biasing the valve I'
+? *, + -,. A relief valve for a positive pressure brake booster, characterized in that the valve body is slidably mounted and is seated on a valve seat with the member on the constant pressure chamber side and the member on the variable pressure chamber side connected. −
