A reaction transmitting mechanism for brake booster in which a reaction from an output shaft is transmitted to an input shaft through a reaction disc, a reaction transmitting member and a valve plunger. An annular member is fitted over the valve body, and is formed with a stepped opening, in which a stepped tubular reaction transmitting member is slidably fitted. The reaction transmitting member is formed with a through-opening, in which the front end of the valve plunger is slidably fitted. The right end face of the flange-like portion of the reaction transmitting member is disposed in opposing relationship with the valve body and the step in the valve plunger. As a result of such arrangement, a more free choice of servo ratios used upon actuating and releasing the brake is allowed as compared with the choice enabled in the prior art.
