VARIABLE GEOMETRY TURBOCHARGER

A variable geometry turbocharger (100) includes: a turbine rotor (2); and a variable nozzle mechanism (12) for adjusting a flow of exhaust gas to the turbine rotor from a scroll flow passage (4) formed on a radially outer side of the turbine rotor. The variable nozzle mechanism includes: a nozzle vane (14, 14B) disposed in an exhaust gas flow passage for guiding the exhaust gas to the turbine rotor from the scroll flow passage; a support wall (16) forming a flow passage wall (28) on a first side of the exhaust gas flow passage with respect to an axial direction of the turbine rotor and supporting the nozzle vane rotatably in a cantilever fashion; and a non-support wall (18) forming a flow passage wall (32) on a second side of the exhaust gas flow passage with respect to the axial direction. Of an end surface of the nozzle vane on a side of the non-support wall, an edge portion (44) on a side of a pressure surface includes a non-support-wall side linear portion (46) formed to have a linear shape.
