Abstract
A brake power servo booster, in which a fluid pressure difference is generated between opposite sides of a power piston, is provided with a wedge shaped member which is forced by the power piston between the wedge shaped recess of the members of an output shaft. When the wedge shaped member is forced into the recess by the piston the distance between the members of the output shaft is enlarged.
