<p>A circular ring-shaped shroud plate is arranged between a scroll passage and a turbine chamber. The shroud plate has a through-hole that penetrates therethrough in a direction along an axis of a turbine shaft. A variable nozzle is supported in an openable/closable manner on the shroud plate by a shaft inserted through the through-hole. A gap between the shroud plate and a turbine housing in the direction along the axis is partitioned into a first space that communicates with an outlet of exhaust gas that faces the through-hole and is provided upstream of a turbine wheel with respect to the flow of exhaust gas, and a second space that communicates with the scroll passage, by a disc spring that is so arranged as to surround the turbine wheel.</p>
