A sealing apparatus has a metal ring having a cylindrical portion and an inward flange portion bending from the open-air side end of the cylindrical portion radially inward; a first sealing member formed integral with the metal ring, and having a first rubber-like sealing lip, and a flange-shaped interposed portion held between the inward flange position of the metal ring and the radial portion of the first sealing member. A second sealing member made of a resin material, extends from the inside-diameter end of the interposed portion axially toward the sealing liquid side, and is located in a gap between the open-air side surface of the first sealing lip and a rotary member, having the inner periphery thereof in slidable close contact with the surface of the rotary member, and regulates radial deformation of the first sealing lip. A screw pumping portion is provided to transport the liquid between the sliding surfaces to the sealing liquid side on rotation of the rotary member.
