Abstract

See full text

A variable nozzle unit includes a variable nozzle vane which is disposed between a hub wall surface and a shroud wall surface and is rotatable around a rotation axis parallel to a rotation axis of a turbine impeller inside a gas flow passage. The variable nozzle vane includes a leading edge, a trailing edge, a hub end surface facing a hub wall surface, and a shroud end surface facing a shroud wall surface. The variable nozzle vane is twisted around a twist center located between the trailing edge and the rotation axis so that the hub end surface protrudes to a radial outside of a rotation axis in relation to the shroud end surface at the leading edge side and the hub end surface protrudes to a radial inside of the rotation axis in relation to the shroud end surface at the trailing edge side.
