とを特徴とする負圧倍力装置。[Claims for Utility Model Registration] A valve body that is arranged to be movable forward and backward in a space formed by a front shell and a rear shell, and that penetrates the rear shell in an airtight and slidable manner, and is connected to this valve body. and a power piston that divides the space into a constant pressure chamber into which negative pressure is introduced and a variable pressure chamber into which air at atmospheric pressure is introduced during operation, and a valve plunger slidably disposed on the valve body. an input shaft connected to the valve plunger and disposed in the valve body so as to be able to move forward and backward; a control valve that is switched and controlled to selectively communicate; A negative pressure booster including an output shaft penetrating a front shell and projecting to the outside, and a reaction disk interposed between the valve body and the output shaft, wherein the output shaft is connected to the reaction disk. The valve body is coupled to the valve body by a bayonet connection so as to be pressed against the valve body with a predetermined initial pressing force, and in this coupled state, the valve body is movable relative to the valve body in the axial direction. Negative pressure booster.
