"textContent": "A labyrinth seal according to one aspect of the present disclosure includes: a first structure; and a second structure opposed to the first structure. The first structure includes: seal fins located at intervals in an axial direction and extending toward the second structure; a downstream wall surface located downstream of a most downstream one of the seal fins and extending toward the second structure, a tip of the downstream wall surface being located at a side of a tip of the most downstream seal fin, the side being close to the second structure in a radial direction; and a first outlet surface extending from the tip of the downstream wall surface toward a downstream side in the axial direction. The second structure includes: a second outlet surface opposed to the first outlet surface, a radial gap being between the first outlet surface and the second outlet surface; and a cavity surface located upstream of the second outlet surface in the axial direction and adjacent to the second outlet surface, the cavity surface being recessed in a direction away from the first structure.",
