ABSTRACT:
For use in a brake booster of the type having a master cylinder disposed rearwardly of a booster mechanism having a power piston and in which a braking reaction force produced on an output shaft is transmitted therefrom to an input shaft through a reaction disc and a reaction transmitting member, an apparatus is provided for adjusting the magnitude of a clearance defined between the reaction disc and the reaction transmitting member. In this apparatus, the input shaft comprises a first section associated with the reaction transmitting member and a second section on which a valve seat is formed. The valve seat forms a valve mechanism disposed within a valve body for controlling the opening or closing of a passage for hydraulic fluid. The first and the second section of the input shaft are formed by separate members, both of which project toward the front shell and are connected together in a manner to permit their relative position to be adjusted. The relative position of the both members can be adjusted through an opening formed in the front shell, thus facilitating the adjustment of the clearance.
