Claims

[Scope of utility model registration request]

In an axial flow rotary machine in which moving blades are provided via a disk fixed to a rotating shaft, and a balance hole is formed through the disk, this An inflow groove formed by cutting out the opening of the balance hole diagonally so as to extend in the rotational direction of the disk, and a protrusion projecting to the opposite side of the inflow groove with the balance hole in between are provided, and the protrusion is provided within the balance hole. An axial flow rotary machine characterized in that a partitioning member is provided with a surface substantially perpendicular to the rotational direction of the disk.
