a valve plunger that is slidably fitted into the valve body and interlocked with the input shaft; an output shaft whose base is slidably fitted into the valve body and faces the valve plunger; and a base of the output shaft. A brake booster comprising a reaction disk interposed between the valve plunger and the brake booster configured to transmit the reaction force of the output applied to the output shaft to the input shaft via the reaction disk and the valve plunger, A first reaction force transmission in which a recess is provided in at least one of the contact surfaces of the reaction disk and the valve plunger where the two members contact each other, and the reaction disk and the valve plunger contact with each other except for the recess. a second path, including the recessed portion, where the reaction disk and valve plunger come into contact;
and a switching point of the reaction force transmission path from the first reaction force transmission path to the second reaction force transmission path as the reaction force increases is set within the servo balance area. A reaction force transmission mechanism for a brake booster characterized by:
