Abstract
A turbocharger includes: a mixed flow turbine including a turbine wheel; a turbine housing configured to house the turbine wheel, including a gas passage extending toward a leading edge of a blade of the turbine wheel; and nozzle vanes arranged in the gas passage in the circumferential direction of the turbine wheel, mutually adjacent two of the nozzle vanes forming a throat therebetween. Each nozzle vane is twisted with respect to a trailing edge of the nozzle vane as a twist center such that a width of the throat becomes narrower on the shroud side than on the hub side.
