るマスタシリンダ。[Claims for Utility Model Registration] Primary side and secondary side seal members are fixedly arranged in the cylinder hole of the cylinder body, and the primary piston and the secondary piston, which are provided with a return port in the seal members, are slid together with a return spring interposed therebetween. In a master cylinder configured to be freely movable, a rod member having flanges at both ends is provided between the primary piston and the secondary piston,
Spring retainers are attached to the inner sides of flanges formed at both ends of the rod member, and the return spring on the primary side is supported between the retainers, and one end of the rod member and one of the spring retainers are connected to the secondary piston. At the same time, the other side of the spring retainer is brought into contact with the front end surface of the cylindrical hole of the primary piston, and the primary piston is brought into contact with the secondary piston depending on the distance from the primary end of the rod member to the bottom surface of the cylindrical hole of the primary piston. A master cylinder characterized by having a set piston stroke until they touch each other.
