Zusammenfassung:	PROBLEM TO BE SOLVED: To generally provide a gas turbine engine, and further actually, its turbine blade. SOLUTION: This turbine blade 16 includes a bade-shaped part 18, a platform 20, a shank 22, and a dove tail 24. The shank 22 includes opposed front face and rear face 46 and 48 corresponding to the front edge and the rear edge 36 and 38 of the blade-shaped part, and opposed first and second side surfaces 50 and 52 corresponding to a positive pressure side surface and a negative pressure side surface 32 and 34 of the blade-shaped part. The shank 22 also includes a projection 56 extending outward from the two side surfaces, and the first projection has an inverse skirt 66 extending outside toward the platform 20, and is joined to a shank rear surface 48. The skirt 66 cooperates with a seal body 58 installed in an engine for reducing leakage between blades. COPYRIGHT: (C)2006,JPO&NCIPI
