徴とする負圧式A negative pressure type in which the power piston is made up of a hub molded from resin and an annular plate molded from a steel plate, and the inner periphery of the diaphragm is airtightly sandwiched and fixed between the inner periphery of the annular plate and the hub. In the booster, a flange portion is formed on the outer periphery of the front end of the hub to abut the inner periphery of the annular plate from the rear, and a plurality of protrusions projecting in the radial direction of the booster from the outer periphery of the flange portion are formed symmetrically with respect to the booster axis. The annular plate is provided with a protrusion that allows the protrusion to penetrate from the rear side to the front side, and a stop member that abuts the front surface of the protrusion is attached to the outer periphery of the tip of the protrusion that protrudes toward the front side of the protrusion. A negative pressure type characterized in that the annular plate and the hub are combined.
