According to an embodiment of the present invention, provided is a master cylinder comprising: a cylinder body having a chamber formed therein to form hydraulic pressure in brake fluid and having a plurality of grooves formed on the outer circumference surface of the inside; a piston installed inside the cylinder body to move in a straight line so that hydraulic pressure can be formed in the chamber and including a relief port having a curved surface formed thereon to introduce the brake fluid into the outer circumference surface; and a plurality of seal cups installed inside a plurality of groove parts and sealing a gap between the piston and the outer circumference surface so that the brake fluid cannot flow out while the inner diameter member is in sliding contact with the piston. Therefore, the brake fluid can be supplied smoothly to the seal cups while ensuring stability.

    본 개시의 일 실시예에 의하면, 내부에는 브레이크 액(brake fluid)에 유압을 형성할 수 있도록 챔버(chamber)를 포함하고, 내부의 외주면에는 복수의 홈부(groove)가 형성되는 실린더 바디(cylinder body); 챔버에 유압이 형성되도록 실린더 바디 내부에 직선운동 하도록 설치되고, 외주면에 브레이크 액이 유입될 수 있도록 굴곡면(curved surface)이 형성된 릴리프포트(relief port)를 포함하는 피스톤(piston); 복수의 홈부 내부에 설치되고, 내경부재가 피스톤에 슬라이딩(sliding) 접촉하며, 브레이크 액이 유출되지 않도록 피스톤과 외주면 사이를 밀봉하는 복수의 씰컵(seal cup)을 포함하는 것을 특징으로 하는 마스터실린더를 제공한다.
