Claims

[Scope of utility model registration request]

A hydraulic chamber is defined by the piston that is slid onto the cylinder body, and a hydraulic chamber that communicates with the hydraulic chamber is defined between the outer periphery of the piston and the inner wall of the cylinder through a suitable communication section provided in the flange of the piston. In the mask cylinder, the supply port of the cylinder body is connected to a narrow width in the direction perpendicular to the axis of the cylinder. A mask cylinder comprising a plurality of holes formed within a region at appropriate intervals in the width direction of the cylinder.
