Claim 7:
8. A variable capacity turbocharger comprising:
a housing;
a turbine impeller at least partially located in the housing;
a scroll flow path located in the housing and encircling the turbine impeller;
a first nozzle ring and a second nozzle ring facing each other in the housing;
a nozzle flow path located between the first nozzle ring and the second nozzle ring and fluidly coupling the scroll flow path to the turbine impeller;
a gap formed between the first nozzle ring and the housing, wherein the gap is located on an opposite side of the first nozzle ring to the nozzle flow path and is connected to the scroll flow path;
a first bearing hole located in the first nozzle ring and including an opening adjacent to the gap; and
a nozzle vane including a first rotation shaft and a second rotation shaft that align along a rotation axis of the nozzle vane,
wherein the first rotation shaft is rotatably supported by the first bearing hole located in the first nozzle ring,
wherein the second rotation shaft is rotatably supported by a second bearing hole located in the second nozzle ring, and
wherein an outer diameter of a portion of the first rotation shaft supported by and located in the first bearing hole is smaller than an outer diameter of a portion of the second rotation shaft supported by and located in the second bearing hole.
