PURPOSE: A turbine device is provided to reduce the rotating speed of a blade arranged in the downstream without influencing to the output of a rotary shaft, thereby reducing an excessive centrifugal load actuated on the blade. CONSTITUTION: A turbine device includes a rotary shaft (120), blades (130) arranged in a plurality of rows along an axial direction of the rotary shaft, and a casing receiving the blades. Gas which is inserted via an inlet (111) of the casing and bumped into the blades is moved to the rear side of the casing. At least the blades of one row among the blades arranged on the rear side of the casing are connected to the rotary shaft by a planetary gear unit (140). The rest of the blades are steadily connected to the rotary shaft. |
