ABSTRACT:
A mounting structure for an air separator in a gas turbine includes an air separator and a rotor blade rotary disk. The air separator includes a cylindrical member with a flange at one end. The rotor blade rotary disk has on its outer face a disk recess portion forming an annular recess around the axial center of the rotor. A sealing face is formed on a contact face between a flange outer peripheral face that is provided on an outer periphery of the flange to be parallel to the axial center of the rotor and a disk recess inner peripheral face opposed to the flange outer peripheral face, that is provided on the disk recess portion and is parallel to the axial center of the rotor and formed around the axial center in an annular shape.
