PROBLEM TO BE SOLVED: To cool a shroud of a turbine engine. SOLUTION: In a shroud sub-assembly 500, intervals of outlets 488, 489 of cooling air passages 480 of side panels 450 adjacent to each other are arranged in two rows in a staggered configuration, the adjacent side panels 450 are combined with a spline seal 492 located on a clearance 502 between the adjacent side panels 450 opposite to each other, of a hump-shaped part 498 positioned at an upper part and crossing the outlets 488, 489 of the cooling air passages 480 to form adjacent shroud segments 422 with the side panels 450 opposite to each other and having spline slots 492. This shroud sub-assembly 500 can provide the uniform collision cooling effective range, and localizes the cooling air more from the outlets 488, 489 of the passages 480.
