Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent an air leakage preventing plate installed fixedly at the end of a leaf seal from falling off at the time of assembly and during operation of an engine. SOLUTION: Two or more circumferentially divided leaf seals 8 close a clearance between the casing of a combustor and a turbine stationary blade structure. The leaf seals 8 are slidably fitted to the casing and a pin directed in the axial direction of the turbine stationary blade structure. The air leakage preventing plate 10 is arranged between the leaf seals 8, 8 adjoined each other in a circumferential direction so as to close the clearance 11 formed between the leaf seals 8, 8. One leaf seal 8 side end of the air leakage preventing plate 10 is fixed to the leaf seal 8 by spot welding 12, and also fitted to the pin through a pin hole 10a. COPYRIGHT: (C)2005,JPO&NCIPI
