A ring seal including sealing lobes is provided to endure rotation and vacuum condition in an assembly process and reduce a manufacturing cost as a design is simple. An outward surface of an axial direction includes a first sealing lobe. An inward surface of an axial direction includes a second sealing lobe sharing an axial central line with the first sealing lobe. A body portion(12) has the outward surface and the inward surface. A tail portion(14) is spread from the body portion. The body portion comprises a radial outside protrusion maintaining the radial position of a ring seal(10). The ring seal comprises a skirt formed in the free end part of the tail portion. The skirt fixes the location of the ring seal.
