An oil sealing system for a turbo charger comprises a housing, a shaft rotatably supported by the housing via a bearing, a turbine-rotor fixed to one end of the shaft, a compressor-rotor fixed to the other end of the shaft, an oil conduit formed in the housing for supplying oil between the shaft and the bearing for lubrication, and an oil sealing device for preventing oil leakage to the turbine-rotor. The oil sealing device comprises, a depression and a drain formed in the housing, a ring-shaped depression and a groove formed on the shaft, and a seal-ring located between the housing and the groove.
