Abstract
A variable geometry turbocharger includes a turbine having a variable nozzle unit, and a compressor. The variable nozzle unit has: a unit main body part that is fixed to a turbine housing and rotatably supports a plurality of nozzle vanes; a drive ring that transmits a driving force to the plurality of nozzle vanes; and a drive ring support member that is fixed to the unit main body part and rotatably supports the drive ring. The drive ring support member is formed by one member and has: base end side parts that regulate movement of the drive ring in a radial direction; tip end side parts that regulate movement of the drive ring to the compressor side; and turbine side receiving parts that regulate movement of the drive ring to the turbine side in the direction of a rotational axis.
