Beschreibung
Zusammenfassung:	A hydraulic mechanism includes an outer cylinder having an expansion side working port and a contraction side working port respectively formed on a top of the outer cylinder; an inner cylinder insertedly installed inside the outer cylinder to come in and out toward a bottom of the outer cylinder; an inner rod having two flow paths respectively connected to the expansion side working port and the contraction side working port, one end of which is fixed to an inner top surface of the outer cylinder, and the other end of which passes through a top of the inner cylinder and protrudes to be positioned inside the inner cylinder; and a piston combined with the other end of the inner rod to be positioned inside the inner cylinder and formed with a hole connected to the flow path of the inner rod connected to the expansion side working port.
