倍力装置の弁機構制御装置。 An operating lever linked to the brake pedal moves the valve mechanism forward and backward to control the fluid pressure applied to the power piston, and a valve plunger that is connected to the tip of the operating lever and constitutes the valve mechanism is used to prevent the brake booster from operating. In a valve mechanism control device for a brake booster, the valve mechanism control device for a brake booster is provided with a stopper member that comes into contact with the inner surface of the sealed shell to restrict the retreating position of the valve plunger. A valve mechanism control device for a brake booster, characterized in that it is equipped with a non-circular cushioning material interposed along the stopper member and fixed thereto by a plurality of protrusions.
