けておく。The cylinder portion is constructed so that it can withstand a sufficient internal pressure by a sealing member such as an O-ring. The shaft box is provided with a hydraulic path for introducing oil to the cylinder and an oil supply port.A quick joint is attached to the oil supply port, and if a hydraulic pump is connected, oil can be supplied to the cylinder. It has a function to seal the oil in the cylinder to prevent it from leaking out. Further, a stopper is provided between the shaft spring seat and the sprung member to prevent the cylinder from moving abnormally.

やその他流体によっても代用が可能である。When adjusting the liner, a hydraulic pump is connected to the oil supply port and hydraulic pressure is applied to move the shaft spring seat upward, so that a gap is formed between the shaft spring seat and the shaft box body. At this time, when the required amount of the liner is inserted and removed and then the hydraulic pressure in the cylinder is removed, the shaft spring seat is lowered and the liner adjustment is completed. Although oil is used in the above-described operation example, water or other fluid may be used instead.
