Abstract
【解決手段】ディフューザ22は、枢動ピン54を中心として複数の位置間で回動可能な複数のベーン38を備える。取付板30が、裏当て板28を支持している。これらのベーン38は、裏当て板28とシュラウド36との間に配列されている。枢動ピン54は、裏当て板28、ベーン38およびシュラウド36と滑合関係にあり、取付板30のボス42に螺入されている。裏当て板28および/またはシュラウド36が撓みを受けている間、取付板30および枢動ピン54の構成によって、裏当て板28およびシュラウド36が互いに平行の状態に維持される。突発的な破損が生じた場合にベーン38を良好に封じ込めるために、一体構造の突起46および/またはボルト40のような構造物が、裏当て板28およびシュラウド36から開口44を通ってベーン38に延びている。
