とするブレーキ倍力装置の消音装置。[Scope of Claim for Utility Model Registration] A valve body provided in a shell so as to be able to reciprocate, a valve mechanism housed in this valve body to control opening and closing of a fluid passage, and an external part that is slidably penetrated through the opening of the shell. a cylindrical portion of a valve body that protrudes from the cylindrical portion of the valve body and has an atmospheric passage therein for introducing atmospheric air into the shell; an input shaft that is inserted through the cylindrical portion of the valve body and interlocks with the valve mechanism;
In the brake booster provided in the atmospheric passage, the brake booster includes a filter member that removes atmospheric dust introduced through the atmospheric passage, and a muffling member that reduces atmospheric intake noise at that time. The filter member is disposed between the shaft and the atmosphere passage, and a recess surrounding the input shaft is formed on the end face of the filter member on the atmosphere side, and the non-ventilating first shielding member and the the input shaft is slidably inserted through the first shielding member and the sound damping member, and the outer peripheral portion of the concave portion of the filter member is closed to the atmosphere side of the filter member. . A noise muffling device for a brake booster, characterized in that a second shielding member is provided in contact with the sound muffling member.
