The piston boss is provided with a large cylinder hole that opens on the front surface and a small cylinder hole that is connected to the back of the large cylinder hole, and the reaction piston that is connected to the input rod is installed in the small cylinder hole, and the output piston is installed in the large cylinder hole. An elastic piston interposed between the output piston and the reaction piston is slidably fitted to each other, and an output rod is integrally disposed in front of the output piston so as to pass through a through hole in the front wall of the booster shell. In a protruding negative pressure booster, the stopper fixed to the front surface of the piston boss allows the output piston to pass if the inclination angle of the output rod with respect to the axis of the large cylinder hole is greater than a predetermined angle θ. A through hole is drilled to prevent the output piston from passing if the angle is less than a predetermined angle θ, and the through hole in the front wall of the booster shell is formed so that the inclination angle of the output rod is restricted to less than the predetermined angle θ by the hole edge. characterized by having done
Negative pressure booster.
