Claims

[Scope of utility model registration request]

Connect the exhaust bypass passage from the inlet of the turbine scroll,
A turbo formed in a turbine casing, provided with an exhaust bypass valve on the discharge side of the exhaust bypass passage, and exhaust gas discharged to the discharge part of the exhaust bypass valve and the discharge part of the turbine rotor from an exhaust outlet pipe. In the exhaust discharge part structure of the charger, an annular surrounding wall is provided along the circumference of the discharge part of the turbine rotor, and the annular surrounding wall is attached to either the turbine casing or the exhaust outlet pipe at a joint surface thereof. 1. An exhaust discharge part structure for a turbocharger, characterized in that the exhaust discharge part structure is formed by extending from the exhaust bypass valve, and the other part thereof is provided with an operating shaft of the exhaust bypass valve.
