Abstract:
A sealing structure of a turbocharger includes a turbine housing including a scroll channel, a nozzle mount, a nozzle plate defining, with the nozzle mount, an exhaust gas channel for introducing an exhaust gas from the scroll channel to a turbine wheel, the nozzle plate including an annular plate portion that has a channel wall surface defining the exhaust gas channel and a tubular portion that extends from an inner peripheral end portion on a back surface of the annular plate portion toward a first inner wall surface of the turbine housing, and a sealing device for sealing a section between the first inner wall surface and an end surface of the tubular portion. The sealing device includes a first plate member that has one surface contacting the end surface of the tubular portion, and a sealing member for sealing a section between the first inner wall surface and another surface of the first plate member, the sealing member being configured to bias the first plate member toward the end surface of the tubular portion.
