Claims

[Scope of utility model registration request]

An oil chamber is formed on the inner periphery of the central part of the cylinder, a plunger or a piston is fitted on both sides of the same chamber, and the tip of the plunger or piston rod is exposed to the outside from both ends of the cylinder. independent oil chambers are formed between the cylinder surface and the plunger or piston rod, and an oil passage that communicates from the outer circumferential surface of the cylinder into the central oil chamber, and an oil passage that communicates with the independent oil chambers on both sides, respectively. A hydraulic cylinder that opens from between the inner and outer circumferences of a cylinder to the outer circumferential surface of the central part.
