A seal ring can protect seal ribs, which have a dynamic load facing a space to be sealed while being smoothly guided to a gap between mechanical elements to be sealed, from foreign materials from the outside. The seal ring is formed as a molded product (1) having a guide ring (2) which is made of cured and hard material, the seal ribs (3,4) applied with the dynamic load, and a seal rib (5) applied with a static load. The first and second seal ribs (3, 4) made of an elastic rubber material are coupled to the guide ring (2). The first seal rib (3) blocks a medium which is to be sealed from the space to be sealed. The second seal rib (4) is formed to block foreign materials (8) from the outside. The first seal rib (3) facing the direction of the space to be sealed from the outside (9) is arranged straight below the second seal rib (4) based on a mechanical function. |
