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.

摘要： To facilitate recycling and prevent rotation of constituent parts, a lip type seal has a first lip seal member constructed from a rubber-like elastic material, a metal-made retaining ring held at the first lip seal member without bonding, and a resin-made second lip seal member and a backup ring which are held at the retaining ring by caulking. The first lip seal member has a tubular portion, a radial portion, a seal lip, and a collar portion. The retaining ring has a cylinder portion, a first flange portion, and a second flange portion, and the second lip seal member and the backup ring are held between the first and second flange portions by caulking. A convex portion is provided at a position in the circumferential direction of the first flange portion, and the convex portion engages with the second lip seal member to prevent rotation of the second lip seal member.
