A cylinder body is joined to a booster shell of a negative pressure booster, a piston is fluid-tightly and movably fitted into a cylinder hole of the cylinder body, and a piston rod portion of the piston is fitted into the rear end of the cylinder hole. In the mask cylinder, the piston rod is slidably supported by a bearing member, and the piston rod is connected to an output rod in the booster shell. A circumferential groove is formed on the outer periphery, a plurality of radial drainage grooves are formed on one side of the disk, and an enlarged diameter step is formed on the periphery of the insertion hole on the other side, and a seal is formed in the circumferential groove and the enlarged diameter step. What is claimed is: 1. A mask cylinder, characterized in that the bearing members are fitted in each other, the bearing member is fitted in series with the rear end of the cylinder hole, and is pressed and fixed to the front part of the cylinder by a locking device having a spring force.
