ダ。 A piston with a center valve slidably held at its tip is slidably provided in a cylinder, and by pushing the piston into the cylinder, a valve spring causes the valve body of the center valve to be attached to the seat surface of the piston. The seat surface is biased and pressed to close the center valve, sealing the pressure chamber and generating hydraulic pressure, and the return spring biases the piston back to close the center valve from the seat surface of the piston. In the master cylinder in which the center valve is opened by separating bodies, the seat surface of the piston is formed into a spherical surface having a radius of curvature that is the same as the radius of gyration of the valve seat surface of the center valve. Cylinder.
