摘要：

An exhaust gas sealing system for a turbocharger including a control valve (41) for controlling a flow of an exhaust gas in a turbine housing (11), a shaft (42) extending to an outside of the turbine housing (11) through a bearing bore (13a) provided on the turbine housing (11), one end of the shaft (42) being fixed to the control valve (41), and a sealing member (43) for preventing the exhaust gas from leaking to the outside of the turbine housing (11) through a gap formed between the bearing bore (13a) and the shaft (42) characterized in that the sealing member (43) includes a through-hole forming a gap with the shaft (42) smaller than a gap formed between the bearing bore (13a) and the shaft (42), wherein one side (43b) of the sealing member (43) is pressed against a sealing face (15a) and is provided within a cavity formed in the turbine housing (11) and including the sealing face (15a) on a peripheral side of the shaft (42). <IMAGE>
