。 An axial flow system having a disk fixedly attached to a rotating shaft and provided with moving blades, a penetrating balance hole formed in the disk, and stationary partition plates facing each other at a distance on both sides of the disk. In a rotating machine, an annular projection concentric with the rotating shaft is provided on a surface near the outer periphery of the disk on the side into which fluid flows, and an annular projection concentric with the rotating shaft is provided on a surface near the outer periphery of the partition plate facing the disk. An axial flow turbine is provided with concentric annular fins and a slight gap is formed between the annular fins and the annular protrusion.
