Abstract
PURPOSE: To fix the positional deviation of a rotary blade in an axial direction thereof securely by a method wherein a fixing hole is provided at a root of the rotary blade while a groove is provided on a rotary disc and a column-shaped fixing component is incorporated into a space between both of them.
CONSTITUTION: A fixing hole 1B is provided at the root of a rotary blade 1, a groove 3 is provided on a rotary disc 3 and a column-shaped fixing component is incorporated into a space between the fixing hole 1B and the groove 3. According to this method, the fixing component 5 is brought to the outside of the rotary disc 3 by a centrifugal force and fixes the rotary blade 1 by functioning as a key, therefore, a positional deviation of the rotary blade 1 in an axial direction thereof due to the maximum grade of thrust force may be fixed surely with the minimum number of component.
