倍力装置の反力機構。[Scope of Claim for Utility Model Registration] A through hole is formed in the shaft of the valve body that is slidably disposed within the shell, and a valve plunger that constitutes a valve mechanism is slidably fitted into this through hole. At the same time, an annular protrusion surrounding the opening of the through hole is formed, a recess is formed in the end surface of the base of the push rod to accommodate the reaction disk, and the annular protrusion is slid into the recess. A brake booster which is movably fitted and brought into contact with the reaction disk and transmits a brake reaction force applied to the push rod to an input shaft connected thereto via the reaction disk and the valve plunger. In the reaction force mechanism, a reaction force transmission member for transmitting reaction force from the reaction disk to the valve plunger is slidably fitted into the through hole between the reaction disk and the valve plunger, and A reaction force mechanism for a brake booster, characterized in that the reaction force transmission member is provided with a seal member that maintains airtightness between a reaction disk and a valve plunger.
