Claims

[Scope of utility model registration request]

A power piston is installed inside the shell to move forward and backward, a pair of pressure chambers are formed in front and behind the power piston, and a pressure chamber is installed outside the shell to detect when an input is applied to the input shaft. A brake booster comprising a control device for advancing the power piston by introducing pressure fluid into a pressure chamber, wherein a holder is disposed on the body of the power piston shaft part so as to be displaceable in the axial direction, and the body and the holder' are connected to each other. A load detector is disposed between the holders, and an input shaft is connected to the holder so that the pedal force applied to the input shaft can be transmitted to the body via the holder and the load detector, and the body, the load A brake booster comprising a gap adjusting means for adjusting a gap between a detector and a holder.
