。 Inside the cylinder hole drilled in the cylinder body,
A piston and a valve stem are inserted movably in the cylinder axial direction, and a fluid communication hole communicating with a reservoir is provided in a fluid pressure chamber defined in the cylinder hole.
When the piston moves forward toward the hydraulic pressure chamber, the valve seal attached to the valve stem is seated on the seal surface on the outside of the opening end of the fluid passage hole on the hydraulic pressure chamber side, thereby establishing communication between the hydraulic pressure chamber and the reservoir. In a center valve type vehicle hydraulic master cylinder that shuts off the
A center valve type vehicle hydraulic master cylinder, characterized in that the sealing surface is formed in a protruding spherical shape.
