を特徴とする気圧式倍力装置。 The inside of the housing consisting of the front shell and the rear shell is defined by a diaphragm into a constant pressure chamber and a variable pressure chamber, and the diaphragm is held by the power piston, and the power piston is controlled by the differential pressure generated between the constant pressure chamber and the variable pressure chamber. In a pneumatic booster that outputs a boosted thrust by moving the diaphragm forward, an annular rib that curves to open toward the front shell is attached to the part that is continuous with the outer folded part of the rear shell that holds the outer bead of the diaphragm. A pneumatic booster characterized by forming:
