特徴とする負圧倍力装置。[Claims for Utility Model Registration] The space formed by the front shell and the rear shell is divided by a power piston between a constant pressure chamber and a variable pressure chamber, by operating an input shaft and switching a control valve. In the negative pressure booster, the negative pressure booster is configured to generate a pressure difference, actuate a power piston using the pressure difference, and output an output via an output shaft that passes through the front shell in an airtight manner by means of a sealing means. The means includes a sealing member and a supporting member for the sealing member, and the supporting member is integrally assembled to the sealing member, and the supporting member is integrally provided with an engaging portion that engages with the front shell. A negative pressure booster characterized by:
