摘要：A seal structure () for sealing a gap between a first structure body () and a

second structure body (). The seal structure includes: a peripheral surface formed on oneof the first structure body and the second structure body; a plurality of seal fins ()provided at intervals in the axial direction so as to form clearances (m) together with theperipheral surface and protrusions that form re-adhesion edges between pairs of axiallyadjacent seal fins; the re-adhesion edges being locations at which leak currents (SL) re-adhere that have passed through a clearance (mA) of an upstream seal fin; and theprotrusions forming first cavities in which eddies (B) are created that flow along theupstream seal fin toward the second structure body, and second cavities in which currents(B) are created that cause a contraction current effect on a clearance (mB) of adownstream seal fin.
