<P>PROBLEM TO BE SOLVED: To provide a seal structure with improved reliability for a gas turbine. <P>SOLUTION: The seal structure 10 for a gas turbine is configured as follows. Annular projecting parts 101, 103 are formed on faces, adjacent to each other, of a plurality of rotor disks so as to face each other while surrounding a rotor shaft. Groove parts 102, 104 are formed along in the circumferential direction on the opposed faces of the projecting parts 101, 103. An outer notch 114 is formed on the opposed face of one rotor disk 202 of the rotor disks 201, 202 facing each other. The groove parts 102, 104 are inserted with both ends of a seal plate assembly 105 in which a plurality of outer seal plates 106 and a plurality of inner seal plates 107, arranged on the inner peripheral side of the outer seal plates 106, are integrated with each other by a rotation preventing member 108. The rotation preventing member 108 is inserted into the outer notch 114. A buffering material 11 is assembled to the groove part 104 so as to suppress a load to the groove part 104 by the seal plate assembly 105. <P>COPYRIGHT: (C)2012,JPO&INPIT |
