PROBLEM TO BE SOLVED: To provide a seal (130) used for a dovetail joint of a turbo machine. SOLUTION: The seal includes a bow-shaped member (220) which has a first end, a center, and a second end, and also includes a sealing means (205) which is provided with at least one sealing member. The sealing member can include a first sealing member connected to the first end and/or a second sealing member connected to the second end. A dovetail joint joints a bucket dovetail (120) and a rotor dovetail groove (110), and a main seal (130) reduces a leak amount of a cooling flow from the dovetail joint. COPYRIGHT: (C)2009,JPO&INPIT
