The present invention pertains to a mechanical seal (1) provided with at least: a rotary ring (3) that reduces gaps in split cross-sections of the mechanical seal (1), and is driven by a rotating shaft of a rotating device so as to rotate; a seal ring (4) that comes into contact with the rotary ring (3) in the axial direction of the rotating shaft; and a gland cover (5) that covers the seal ring (4) and the outside thereof in a sealed state. The mechanical seal (1) is further provided with: protruding sections (80 to 83) that split at least the rotary ring (3), the seal ring (4) and the gland cover (5) in the radial direction, and that protrude toward one surface of the split surface (58) of at least the gland cover (5) and the other surface of the split surface (58); and recessed sections (70 to 73) that mate with the protruding sections on the other surface. |
