PURPOSE:To simplify constitution by installing a segment by way of a plurality of bellows whereby arranging driving fluid feeding systems to a plurality of bellows in parallel. CONSTITUTION:A fin segment 4 is installed on an installation groove 10 of a nozzle outer ring 3 by way of a plurality of bellows 12 and 13. And the nozzle outer ring 3 is formed with feeding passages 31 and 32 for driving fluid to a plurality of bellows 12 and 13 whereby the passages 31 and 32 are communicated with a circular passage 33 formed on the outer circumferential surface of the nozzle outer ring 3. This constitution can comprise a bellows driving fluid feeding system simply. |
