Claims

[Scope of utility model registration request]

a cylinder body having a cylinder open at one end, first and second inlets, and first and second outlets; a primary piston forming a first supply chamber in constant communication with the second inlet; a second supply chamber fluid-tightly and slidably fitted within the cylinder and in constant communication with the second inlet; a secondary pressurized fluid chamber that is always in communication with the first outlet and forms a first pressurized fluid chamber between the primary piston and the first outlet; and a second pressurized fluid chamber that is always in communication with the first outlet and between the cylinder and the end wall of the cylinder. a retainer which is attached to the first pressurized liquid chamber so as to be spaced apart from the primary piston by a predetermined amount and which can come into contact with the secondary piston; A second return spring is installed in the second pressurized liquid chamber to urge the secondary piston toward the primary piston and whose set load is smaller than the set load of the first return spring, communication between the first pressurized liquid chamber and the second pressurized liquid chamber and the first inlet and the first inlet in conjunction with sliding of the primary piston and the secondary piston from their respective return positions; In the tandem master cylinder, the return position of the secondary piston is set by contact between the secondary piston and a stop pin fixed to the cylinder body; The assembled body of the primary piston, the retainer, and the first return spring is integrally freed by a small amount between the secondary piston and the stopper fixed to the cylinder opening of the cylinder body, in which the assembly is in the return position. A tandem master cylinder that is slidable.
