にしてなることを特徴とするターボドリルの軸封装置。A shaft with a bit attached to the tip is inserted into the housing, and a bearing supports the rotation of the shaft and the reaction force of the bit during excavation, and a multi-stage turbine generates rotational force on the shaft using the pumped fluid. In a turbo drill equipped with a part, a steel bearing is used as the bearing, and a high-pressure mechanical seal is installed on the bit side between the bearings in order to lubricate the bearing located between the bit and the turbine part in an oil bath. On the turbine side, a double structure seal consisting of a low-pressure mechanical seal and an oil seal is arranged to seal in oil, and one side is connected to the oil seal in an oil reservoir provided in the housing so that the shaft does not rotate and slide. A balance piston that slides only in one direction is housed, and the other side of the oil sump is opened to the pressure fluid side, and as the pressure in the bearing decreases, the balance piston moves and the oil in the oil sump flows out to the bearing. A shaft sealing device for a turbo drill, characterized in that the shaft sealing device is configured so as to
