Claims

[Scope of utility model registration request]

A nozzle vane is disposed in a gas flow path from the turbine inlet chamber to the turbine wheel, one end of the vane shaft fixed to the nozzle vane protrudes outside the turbocharger housing, and the vane shaft is rotated within a bush fixed to the housing. In the turbocharger which is movably supported, the gap formed between the vane shaft and the bushing is connected to a compressor outlet chamber via a compressed air flow passage to send compressed air between the vane shaft and the bushing.
