に備えていることを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 provided with an engaging portion that penetrates the sealing member in a radial direction and engages with the front shell. Negative pressure booster.
