PROBLEM TO BE SOLVED: To provide a mechanism for adjusting nozzle, which is trouble-free in abrasion and friction. SOLUTION: The mechanism 50 for adjusting nozzle includes a fixing ring 52, at least one vane 56 coupled to the fixing ring 52 by means of a pivot pin to rotate together with the pivot pin, an adjusting ring 54 coupled rotatably to the fixing ring 52 to rotate around a vertical axis Z of the mechanism 50 for adjusting nozzle, and a coupling mechanisms 58, 60 for coupling at least one vane 56 to the adjusting ring 54 to move at least the one vane 56 when the adjusting ring 54 rotates. The coupling mechanisms 58, 60 include a lever constituent 58 and a link constituent 60 which are coupled to each other. The lever constituent 58 is coupled to at least the one vane 56, while the link constituent 60 is coupled to the adjusting ring 54. COPYRIGHT: (C)2011,JPO&INPIT |
