徴とする液圧ブレーキ倍力装置。 A power piston is slidably housed in the housing and provides a driving force to a master cylinder piston provided on one side of the power piston; A pressure chamber for applying hydraulic pressure to the power piston; and a rod guide located on the pressure chamber side of the power piston and provided in the housing so as to be slidable on the axis of the power piston. In the hydraulic brake booster, the input rod is guided by the rod guide. and a small diameter part formed on the tip side of the input rod to have a smaller diameter than the large diameter part, and the small diameter part is fitted into the power piston so as to be slidable in the axial direction. A reaction force chamber is formed at the back of the input rod inside the power piston, and has the same diameter as the small diameter part of the input rod, and is separated from the pressure chamber. A hydraulic brake booster, characterized in that the hydraulic brake booster is selectively connected to the reservoir or the pressure chamber via the hydraulic brake booster.
