The shaft box is provided with a hydraulic path and oil supply port for introducing oil into the cylinder section, a quick joint is attached to the oil supply port, oil can be supplied to the cylinder by connecting a hydraulic pump, and when the hydraulic pump is removed A function to seal the oil in the cylinder so that it does not escape to the outside is provided. Further, a stopper is provided between the shaft spring seat and the sprung member so that the cylinder does not abnormally move.

やその他流体によっても代用が可能である。At the time of adjusting the liner, the hydraulic pump is connected to the oil supply port, and the hydraulic spring 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, if a required amount of the liner is inserted and removed, and then the oil 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 working example, it can be replaced by water or other fluids.
