Abstract
An exhaust gas sealing system for a turbocharger includes a control valve for controlling a flow of an exhaust gas in a turbine housing, a shaft extending to an outside of the turbine housing through a bearing bore provided on the turbine housing, one end of the shaft being fixed to the control valve, and a sealing member for preventing the exhaust gas from leaking to the outside of the turbine housing through a gap formed between the bearing bore and the shaft. The sealing member includes a through-hole forming a gap with the shaft smaller than a gap formed between the bearing bore and the shaft. One side of the sealing member is pressed against a sealing face and is provided within a cavity formed in the turbine housing and including the sealing face on a peripheral side of the shaft.
