ABSTRACT:
A power-servo booster having a shortened overall length and lighter weight. A fitting member disposed within a connection hole in a power piston is cylindrically formed and a reaction disk is disposed within the cylindrical fitting member. An annular groove is formed in an outer periphery at the bottom of the connection hole and the power piston. A portion of the power piston within the annular groove projects towards the push rod and the reaction disk disposed within the fitting member is placed within the connection hole so that it can contact with an end surface of the projecting portion. The peripheral end of the fitting member is adapted to fit within the annular groove. An annular gap is formed between the fitting member and the bottom of the annular groove to allow for deformation of the reaction disk.
