キブースタ。[Claims for Utility Model Registration] A power piston that operates according to the pressure difference on both sides, a large diameter plunger that is fitted into a large diameter part of a stepped hole formed in the power piston and transmits force to an output member, A small-diameter plunger connected to the input member and fitted into the small-diameter portion of the stepped hole; and a small-diameter plunger disposed in the large-diameter portion between the large-diameter plunger and the small-diameter plunger so that the and a reaction member made of a soft elastic body that distributes reaction force to the small diameter plunger and the power piston, and is applied to the input member at a multiplication factor according to the pressure receiving area ratio of the large diameter plunger and the small diameter plunger to the reaction member. In the brake booster, the small-diameter plunger is formed with a plurality of stepped end faces, and the rear axis member is superimposed on each of the end faces in a stepped shape that can be press-contacted with each other. The small-diameter plunger has a plurality of layers, and the gap between each end face of the small-diameter plunger and each layer of the reaction member facing them is set such that the pressure receiving area of the small-diameter plunger against the reaction member increases as the small-diameter plunger moves forward. A brake booster characterized in that the brake booster is differentiated in stages so as to increase in stages.
