タシリンダ。 A cylinder body in which cylinder bores of a large diameter portion and a small diameter portion are formed in series, a valve chamber interposed between the cylinder body and a reservoir tank, and a large diameter of the cylinder that communicates the valve chamber and the cylinder body. In a master cylinder that has a supply hole formed near the boundary between the bore and the small diameter bore and a compensation hole formed on the small diameter bore side, the valve chamber is always required when there is a difference between the cylinder side hydraulic pressure and the reservoir side hydraulic pressure. A relief part is formed so that the minimum pressure liquid flows to the low pressure side and eliminates the difference in liquid pressure, and the piston in the cylinder body has a small diameter part on its head side that fits into the small diameter bore of the cylinder, and a tail end. At the same time, a flange-shaped stopper having a smaller diameter than the small diameter portion is formed at a predetermined portion on the head side of the piston, and a predetermined mounting load is set between the stopper and the retainer. A master cylinder characterized in that a slider that is liquid-tight and movable in the axial direction is interposed between the large diameter bore and the piston, which are biased toward the stopper by a coil spring.
