Claims

[Scope of utility model registration request]

A mask cylinder with a structure in which a primary piston and a secondary piston that individually generate two systems of hydraulic pressure are slidably provided in the cylinder, and the secondary piston returns to its initial position by mechanical connection with the primary piston when pressure is reduced. a spring whose one end abuts the primary piston and the other end inserts into and abuts the secondary piston;
1. A mask cylinder comprising a return spring having one end in contact with a large diameter portion formed on the opposite side of the primary piston with which the spring abuts, and the other end in contact with a cylinder stepped portion.
