Beschreibung
Zusammenfassung:	A rotary machine 100 includes a bearing 10, a rotary shaft 20, a turbine wheel 30, a turbine nozzle 31, and a first cavity 40. The bearing 10 has a first end face 10a and a second end face 10b each positioned in the axial direction of the rotary shaft 20. The distance from the first end face 10a to the turbine wheel 30 is shorter than the distance from the second end face 10b to the turbine wheel 30. The first cavity 40 is positioned, in the axial direction of the rotary shaft 20, between a back surface 31b of the turbine nozzle 31 and the second end face 10b of the bearing 10 or between the back surface 31b of the turbine nozzle 31 and a space 11 that the second end face 10b of the bearing 10 faces. The first cavity 40 is present in the zone overlapping with the turbine nozzle 31 in a radial direction of the rotary shaft 20.
