Abstract: Disclosed herein are a sealing member for a master cylinder and a master cylinder having the same. The master cylinder is configured such that a communication hole of a piston is rapidly brought into communication with an oil path toward an oil tank upon release of braking. This may minimize meaningless retracting movement of the piston and delay in a braking release operation. The sealing member for the master cylinder includes an outer wing part to come into contact with the cylinder body, and an inner wing part to come into contact with the outer surface of the piston. The inner wing part includes a seal formed at a tip end thereof and at least one oil passage formed in a surface thereof opposite the outer surface of the piston.

Abstract: Disclosed is a hydraulic brake booster. A relative movement structure of a control plunger and an output shaft is modified in such a manner that the output shaft operates in the control plunger, thereby reducing the overall length of the booster and the manufacturing cost. An inner circumferential surface of a guide of the control plunger does not make contact with an outer circumferential surface of the output shaft, so that the vibration and the impact caused by the contact between the control plunger and the output shaft are not delivered, thereby improving brake pedal feeling. The control plunger includes a guide having a groove, and an inner diameter of the guide is greater than an outer diameter of the output shaft. The control plunger and the output shaft perform relative movement in the overlap state therebetween, thereby reducing the overall length of the booster and the manufacturing cost.
