とする負圧式倍力装置。 A booster piston that accommodates the inside of the booster shell so as to be able to reciprocate back and forth; and a booster piston that overlaps the rear surface of the booster piston to connect the inner peripheral bead to the booster piston and connect the outer peripheral bead to the peripheral wall of the booster shell. a first working chamber at the front that is connected to a negative pressure source, and a second working chamber at the rear that is selectively communicated with the first working chamber or the atmosphere through a control valve linked to an input member. , the booster piston is composed of a disc part and a boss part passing through the center of the disc part and connected to the disc part, and fixing a return spring that springs the booster piston in a backward direction. A negative pressure booster having an end supported on the front wall of the booster shell and a movable end supported on the booster piston, the negative pressure booster having a plurality of insertion holes extending in the circumferential direction and having the movable end of the return spring supported on the front surface. A supporting connecting flange is integrally provided on the boss portion, a plurality of locking pawls passing through each of the insertion holes are provided on the front surface of the disk portion, and the inner periphery where each locking pawl is fixed to the disk portion. A negative pressure booster, characterized in that a bead is crimped to the rear surface of the connection flange and protrudes to be locked to the movable end of the return spring.
