とするブレーキ倍力装置。[Scope of Claim for Utility Model Registration] A shell, a cylindrical protrusion that is opened by protruding the rear center part of the shell, and a rear cylinder that is slidably disposed within the shell. A valve body having a shaped part slidably passed through the cylindrical protrusion and protruded to the outside, a valve mechanism housed in the valve body, and a valve plunger constituting this valve mechanism to control the flow of the valve mechanism. A brake booster comprising an input shaft for switching and controlling the path, and a key member that is interlocked with the valve plunger and restricts free retreat of the valve plunger when not in operation to reduce stroke loss of the input shaft, A stopper plate is attached to the inner wall surface of the attachment portion of the shell to the vehicle body, and a minute gap is provided between the inner wall surface of the shell and the facing surface of the stopper plate, and the stopper plate is attached to the cylindrical protrusion. A brake booster characterized in that the valve plunger is protruded radially inward from an inner diameter of the valve plunger, and the key member is brought into contact with the protrusion to restrict free retreat of the valve plunger.
