PROBLEM TO BE SOLVED: To provide a seal ring having high sealability and sufficient assemblability.SOLUTION: A seal ring is annularly formed with centering on a center axis. The seal ring includes a first end and a second end. The first end includes a first vertical surface extending vertically to the center axis, a first parallel surface extending in parallel with the center axis from a first edge on an inner peripheral side of the first vertical surface, and a first engagement part provided on the first vertical surface with an interval from the first edge. The second end includes a second vertical surface extending vertically to the center axis and brought into surface contact with the first vertical surface, a second parallel surface extending in parallel with the center axis from a second edge on an inner peripheral side of the second vertical surface and brought into surface contact with the first parallel surface, and a second engagement part provided on the second vertical surface with an interval from the second edge and engaged with the first engagement part.SELECTED DRAWING: Figure 2 |
