Claims

[Claims for Utility Model Registration] A turbine housing in which a turbine wheel is housed and a compressor housing in which a compressor impeller is housed are joined through a center housing, and both ends of the shaft supported by the center housing are connected to each other as described above. In a turbocharger that rotatably passes through a turbine housing and the compressor housing and is coupled to the turbine wheel and the compressor impeller, the center housing and the shaft are separated in the circumferential direction by a joint between the center housing and the shaft. 1. A seal structure for a turbocharger, characterized in that a seal ring is provided, and steps are formed at opposing ends of the abutment portions of the seal ring so that they overlap each other in the circumferential direction.
