Abstract
A seal segment (11) includes a retainer (21), a seal body (13) having a thin plate seal piece (20), a high-pressure side plate (23), a low-pressure side plate, a retainer simulating section (51) further extending in the circumferential direction (Dc) from an end portion of the retainer (21) in the circumferential direction (Dc), and a block body (50) including a seal body simulation section (53) extending inward in the radial direction (Dr) from the retainer simulation section. The high-pressure side plate (23) and the low-pressure side plate cover at least a part of the seal body simulation section (53) of the block body (50).
