Claim 18:
19. 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 bearing hole located in the first nozzle ring and including an opening adjacent to the gap; and
a nozzle vane located in the nozzle flow path, wherein the nozzle vane includes:
a first rotation shaft inserted into the bearing hole located in the first nozzle ring; and
a second rotation shaft inserted into a second bearing hole located in the second nozzle ring, and
wherein an inner diameter of the opening adjacent to the gap is smaller than an outer diameter of the second rotation shaft inserted into the second bearing hole.
