Abstract
An object is to provide a variable-geometry exhaust turbocharger including a variable nozzle mechanism in which nozzle supports may not deform under a high-temperature condition. A variable-geometry exhaust turbocharger () includes: a nozzle mount (); a nozzle support () having a first end coupled to a first face () of the nozzle mount; a nozzle plate () coupled to the second end of the nozzle support and supported to be separated from the first face () of the nozzle mount, the nozzle plate having a first face () coupled to the nozzle support and a second face () which is opposite to the first face and which faces an exhaust gas channel () through which exhaust gas flows: a plurality of nozzle vanes () rotatably supported between the nozzle mount and the nozzle plate; and a variable nozzle mechanism () configured to change vane angles of the nozzle vanes to control a flow of the exhaust gas flowing between the nozzle mount and the nozzle plate. The nozzle plate is formed of a material having a smaller linear expansion coefficient than that of a material forming the nozzle mount.
