レーキ倍力装置の消音装置。[Scope of Claim for Utility Model Registration] A power piston that is movable forward and backward within the shell, a constant pressure chamber and a variable pressure chamber formed before and after the power piston in the forward and backward direction, and a valve provided within the valve body of the power piston shaft. and an input shaft connected to a valve plunger constituting the valve mechanism, the input shaft is advanced to switch the flow path of the valve mechanism, and to cut off communication between the constant pressure chamber and the variable pressure chamber. In a brake booster in which a variable pressure chamber is communicated with a pressure fluid source to advance a power piston, the variable pressure chamber is formed between the inner circumferential surface of the valve body and the outer circumferential surface of the valve plunger, and is connected to the variable pressure chamber. 1. A sound damping device for a brake booster, characterized in that a sound damping member such as an air filter is disposed in a gap constituting a part of a passage communicating with the brake booster.
