ール機構。[Claims for Utility Model Registration] (1) A shaft, a turbine rotor fitted on the shaft, a housing rotatably supporting the shaft via bearing means, and a space between the housing and the shaft. A turbocharger having a seal ring disposed in the shaft, a seal ring groove formed in the shaft, and a recess between the bearing means of the housing and the seal ring. A turbine side oil seal mechanism for a turbocharger, wherein a screw portion is formed on an outer circumferential surface of the shaft on the side of the bearing support portion, and a radial groove is formed on the outer circumferential surface of the shaft on the side of the bearing support portion of the shaft from the screw portion. (2) A protrusion is provided in a portion of the concave portion of the housing adjacent to the shaft, extending over the circumference of the shaft, so that the lubricating oil located in the radial groove is applied to the shaft by centrifugal force caused by the rotation of the shaft. 2. The turbine-side oil seal mechanism for a turbocharger according to claim 1, wherein the oil is blown to the bottom of the protrusion of the recess, travels along the outer periphery of the protrusion, and falls below the turbocharger. (3) The radial groove has a tapered shape that decreases from the bearing support portion of the shaft toward the screw portion.
) The turbine side oil seal mechanism of the turbocharger described in ).
