Abstract

Provided is a turbine housing of a turbosupercharger provided in an exhaust passage of an internal combustion engine, in which the turbosupercharger has a turbine wheel provided in the exhaust passage, and an outlet of the turbine housing is connected with an exhaust pipe in which an air- fuel ratio sensor is provided. A protruding part is provided in the turbine housing. The protruding part is provided on an inner periphery surface of the turbine housing, and is provided in a given region in a circumferential direction at a position closer to the outlet of the turbine housing than the turbosupercharger. Further, the protruding part guides exhaust gas so that the exhaust gas is sent out from the outlet of the turbine housing towards the exhaust pipe, while restraining diffusion of the exhaust gas discharged from the outlet of the turbine housing towards the exhaust pipe The exhaust gas is discharged while turning by the turbine wheel.
