置の反力機構。[Scope of Claim for Utility Model Registration] A large-diameter hole and a small-diameter hole are connected to the shaft of a valve body that is slidably disposed within the shell, and the base of the push rod is placed in the large-diameter hole and the valve body is placed in the small-diameter hole. The valve plungers constituting the mechanism are slidably fitted into each other, and a recess is formed in the base end face of the push rod to house a reaction disk therein, and a stepped portion between the large diameter hole and the small diameter hole is formed. forming an annular groove on the end face and protruding an annular projection protruding toward the push rod around the small diameter hole, and inserting the annular projection into the recess of the push rod;
In the reaction mechanism of the brake booster, the reaction force of the brake applied to the push rod is transmitted to the valve plunger and the input shaft connected thereto via the reaction disk, wherein an elastic body is housed in the recessed part of the push rod. A reaction mechanism for a brake booster, characterized in that the reaction disk is brought into pressure contact with the annular protrusion by the elastic force of the elastic body when the brake booster is in a non-operating state.
