<P>PROBLEM TO BE SOLVED: To provide a seal structure capable of suppressing a leakage loss by sufficiently developing the high performance seal effect of a brush seal on a steam turbine and a gas turbine with a moving blade with a blade-integrated cover. <P>SOLUTION: In this seal structure of the moving blade tip part, only the brush seal 19 of fixed parts (stationary body side) 13 is disposed between adjacent steps 14 and 15 formed at the tip part of the moving blade with the blade-integrated cover on the stationary body side, and the position of the brush seal 19 is not located on the outer peripheral surface of a contact surface between the covers. <P>COPYRIGHT: (C)2004,JPO |
