In this lip seal, the inner diameter portion of the sheet protrudes toward the sealed fluid side and slides into sliding contact with the outer circumferential surface of the rotating shaft with an appropriate interference to prevent leakage of the sealed fluid. A lip seal characterized in that a required number of protrusions for fixing a metal case are protruded at required positions in the axial direction. (2) The lip seal according to claim 1, wherein the protrusion has an annular shape. (3) The lip seal according to claim 1, wherein the protrusion has a substantially spherical shape, and a plurality of protrusions are arranged circumferentially in the axial direction of the metal case. (4) The lip seal according to claim 1, wherein the protrusion is fitted into a recess provided on the inner periphery of the housing.
