摘要： In a variable nozzle unit, at a position located away from and opposed to a first nozzle ring in a right-left direction, a second nozzle ring is provided integrally with the first nozzle ring through multiple connecting pins arranged in a circumferential direction. An inner edge portion of a support ring is connected to the first nozzle ring by riveting of one end portions of the multiple connecting pins. Each pin hole in the support ring is formed into such a shape extending in a radial direction of the support ring. A washer is provided between a rim of each pin hole in the support ring and a rivet head brought about by joining of the end portion of the corresponding connecting pin.

摘要： 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.

摘要： A projecting portion is formed on a nozzle ring, projects to a radially outer side with respect to a cylindrical portion, extends in a circumferential direction, and is held in abutment against a housing from a side of a link plate. A plate is faced to the nozzle ring on a side of a nozzle vane, and is configured to form a flow passage in a clearance to the nozzle ring. A pin is inserted into a first insertion portion formed in the nozzle ring and a second insertion portion formed in the plate, and to which the nozzle ring and the plate are mounted while the clearance is maintained. A counter bore groove is formed in the first insertion portion of the nozzle ring on the side of the link plate, and cut out the projecting portion.
