Abstract
A master cylinder (1) has a cylinder housing (2) composed of a body (3) having an opening at one end thereof and a cap (4) screwed into the opening of the body; pistons (6, 7) installed movably and guided and supported by a piston (5) and guide sleeve (10) in the cylinder housing; and pressure chambers (8, 9) in the housing in communication with a reservoir (2, 6) via through holes (13, 14) which are closed to cut off communication between the pressure chambers and the reservoir as the pistons move into the pressure chambers during application of the pistons to send under pressure the fluid in the pressure chambers to an operation system. A piston guide section (17) extending in the radial direction is integrally formed on the inner peripheral surface of the cap, and a passage (25) having one end (25a) open on the sliding surface of the piston (6) and the other end (25b) in communication with the reservoir (26) is formed in the cap.
