たマスタシリンダ。 A pair of sealing devices provided in the cylinder hole of the cylinder body with a sleeve placed between them, a pair of pistons inserted movably through each sealing device, and a space between the pair of pistons and one of the pistons. and a pair of fluid passages formed independently from the hydraulic fluid reservoir to each sealing device, and a pair of fluid passages formed in each piston to connect each pressure chamber and each fluid passage. A small hole that communicates when inactive,
and a discharge part formed in communication with each pressure chamber, and the discharge part connected to the pressure chamber between the pair of pistons functions by engaging with the engaging part of one piston when the one piston moves excessively. In the master cylinder provided with a hydraulic pressure control valve that is released, the engaging portion of the one piston is formed by integrating a member having a protrusion that movably fits into a groove formed in the sleeve.
