A seal body has an unassembled form having a ring shape, wherein in an assembled state the seal member is received in the annular groove of the rotating shaft with the seal member flipped with a first side surface facing radially inward toward the annular groove and a second side surface facing radially outward toward the bore, the first side surface along a cylindrical outer diameter surface being lifted off of a bottom surface of the annular groove so that the second side surface along the outer diameter surface engages the inner bore surface while the second side surface along an inner diameter surface is spaced from the inner bore surface.
