PURPOSE:To prevent damage of a moving vane, by a method wherein a moving vane made of ceramic is held between the nip formed by the support parts of vane lock bodies located in grooves in the outer perphery of a disc. CONSTITUTION:A vane lock body 3 is engaged with a groove 1 in the outer periphery of a disc 2, and a moving vane 4 is held between the nip formed by adjoining support parts 14, formed in a claviform shape in cross section, of the vane support body 3. This, even if the vane is brought to a condition in which thermal stress and mechanical stress are produced, enables relieving of such stress, resulting in the possibility to prevent damage of a moving vane made of ceramic. |
