A double-lip type sealing member is arranged on the inner wall of the hydraulic cylinder hole, and the inner lip of the sealing member is liquid-tightly engaged with the outer peripheral surface of the plunger to close the hydraulic cylinder body. In the brake booster, the brake booster is provided with a fluid compensation hole in the plunger which is divided into a hydraulic pressure chamber and a fluid replenishment chamber, and communicates the hydraulic pressure chamber and the fluid replenishment chamber when the plunger is in the retracted position. A brake booster in which the inner diameter of the base is larger than the outer diameter of the plunger to form a gap therebetween, and the liquid compensation hole is opened in the gap when the plunger is in a retracted position.
