Claims

[Scope of utility model registration request]

A communication passage that opens from the reservoir tank to the outer periphery behind the primary cup of the primary piston is formed in the axial direction in the cylinder casing, and an orifice hole that opens into the hydraulic pressure chamber of the primary piston from the middle of the communication passage. A mask cylinder characterized in that it is formed by drilling or punching from the inside facing the hydraulic pressure chamber.
