とするターボチヤージヤの軸封装置。 In a shaft sealing device for a turbocharger, which is equipped with two ring seals for sealing a rotating shaft between a compressor and a bearing chamber, and in which the space sandwiched between these ring seats is communicated with the atmosphere, the two rings are attached to the housing side. The fitting portions that slidably support the outer peripheries of the seals are formed with a single cylindrical surface, and a stepped portion is formed on one end of the fitting portion located on the impeller side to which one ring seal comes into contact. A shaft sealing device for a turbocharger, characterized in that two annular grooves are formed on the rotating shaft side to engage each of the two ring seals with a predetermined side clearance.
