設したことを特徴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. diaphragm, the front first working chamber connected to the negative pressure source and the first working chamber are connected to the negative pressure source.
An output rod is provided on the front surface of the booster piston, the output rod being partitioned into a working chamber or a second working chamber at the rear which is selectively communicated with the atmosphere, and abutting the working piston of the master cylinder with a spherical surface on the front surface of the booster shell. An output piston and an elastic piston of a reaction mechanism that feed back a part of the operational reaction force of the output rod to the input side are arranged in front of and behind a hole opening in the front surface of the booster piston, and the output In the negative pressure booster in which the output rod is protruded from the front surface of the piston, an elastic cylinder is fitted between the inner circumferential surface of the hole and the outer circumferential surface of the output piston to allow the swing of the output rod. A negative pressure booster characterized in that a cushion part is connected to the front end of the elastic piston and can abut against the front wall of the first working chamber, and is connected to the front end of the cylinder body.
