Abstract
PURPOSE:To prevent a leakage or passage of steam along the concave portion between the tenons and to improve a thermal efficiency by a method wherein a calking shape at the tenons projected from a leading end of each of the movable vanes is made to be a specific shape. CONSTITUTION:A leading end surface of the movable vane 2 is formed in an arcuate shape, and the tenon 3 of a part of the movable vane 2 (shown by a two-dot broken line for its condition before its calking) is projected from a central part of the movable vane 2. The cover 1 for the movable vanes covers each of the leading ends of a group of movablve vanes 2, and the cover has holes through which the tenons 3 are projected. By calking the tenons 3 at the height of H, the cover 1 is fixed to a group of movable vanes 2. In this case, the calking part 3a for the tenons becomes a rectangular column shape having a cross section of substantial parallelogram. The side walls 3a1 and 3a2 facing each other located along the direction crossing the rotation direction (arrow 6) of the movable vanes of the rectangular column are made to be positioned obliquely from the delayed side toward the leading side of the movable vanes along the direction from the steam inlet side 9 to the steam outlet side 10.
