SEAL RING MOUNTING METHOD FOR TURBOCHARGER, AND TURBOCHARGER

It is intended to provide a seal ring mounting method for a turbocharger and a turbocharger with the seal ring, whereby the seal ring is less likely to be affected by other parts. An annular protrusion (12j) for restricting a position of a seal ring (16) in the radial direction is provided at a tip portion (12h) of an inner peripheral wall (12b) of a turbine housing (12), and the seal ring (16) is mounted between a side surface (36c) of a nozzle plate (36) and a first step portion (12k) of the tip portion (12h) of the inner peripheral wall (12b) so that the outer periphery of the seal ring (16) is restrained by the annular projection (12j).
