PROBLEM TO BE SOLVED: To increase durability of a turbine nozzle for a gas turbine engine and to improve the constitution of a division line for prolonging its useful life. SOLUTION: The turbine nozzle 18 comprises segments 18a of the outer and inner bands 30, 32 that support a pair of corresponding blades 28. The bands are adjacent to each other at corresponding end parts 42, 44 along a division line 46, and each band has a front land, rear land on the other side of the front land, and intermediate land extending between these two lands. The front land has a nominal, step 48 facing rearward, the rear land has a nominal step 50 facing forward, and the intermediate land constitutes a nominal same plane. |
