摘要： A sealing device and a sealing structure in which sliding ability is stabilized are provided. A lip tip of a first seal lip (120) includes a first tapered surface (123a) which expands in diameter toward a sealed fluid side (L) and a second tapered surface (123b) which expands in diameter toward an opposite side (A) of the sealed fluid side, the second tapered surface (123b) is provided with a plurality of screw thread protrusions (or screw thread grooves) (124) which move grease (170) in the axial direction while rotating relative to a rotary shaft (21), and each of the plurality of screw thread protrusions (or screw thread grooves) (124) is disposed so as to move the grease (170) toward the opposite side (A) of the sealed fluid side.
