PURPOSE:To provide an axial flow turbine device which can be continued to operate without generating a trouble of seizure or the like in stationary and moving blades even when external force of impact, bending, etc., acts on a casing. CONSTITUTION:A sliding member 8 of material of hardness smaller than the material of a stationary blade 3 is mounted on an external surface of a moving blade collar 6 facing to the internal peripheral end of the stationary blade, and a sliding member 9 of material of hardness smaller than the material of a moving blade 5 is mounted on an internal surface of a moving blade collar 7 facing to the external peripheral end of the moving blade. |
