    摘要： In a sealing device (1) , in which a main seal lip (6) used for a shock absorber is formed in a one-stage seal lip structure, for the purpose to improve friction characteristics while securing sealing performance, a roughened portion (63) to which satin finishing is applied to form projections and recessions on the surface thereof is formed on the sliding surface (61) of the main seal lip (6) slidably moving on a contacting member at a position apart a specified distance from a lip edge (62). An area between the lip edge (62) and the portion where the roughened portion (63) is formed is a plane portion (64) to which the satin finishing for forming irregularities is not applied. In place of the satin finishing, a plurality of axially extending projections (65), concave threads (67), or lattice-shaped projections (68) may be formed on the roughened portion.

    摘要： A resin lip type seal (1) capable of increasing safety against rupture by reducing the rigidity of a plate-like lip (4) bent about the tip point A of a roughly wedge-shaped recessed part (8) to reduce stress concentration at the point A, suppressing the lowering of sealability due to a reduction in the creep of the lip, and increasing the follow-up capability of the lip to the eccentricity of its axis. Slits are formed in the slidable contact surface (41) of the plate-like lip (4) or/and the anti-slidable contact surface (42) thereof. Slits (7) are also formed in the sloped slidable contact surface (21) of the inner lip (2) of the seal. Then, the ratio of the portion of each of the slidable contact surfaces where the slits (7) are formed is set to ½ or more of each of the surface areas of the slidable contact surfaces (21, 41, 42

    摘要： A resin lip type seal (1) capable of increasing safety against rupture by reducing rigidity of a plate-like lip (4) bent around a tip point A of a approximately wedge-shaped recessed part (8) to reduce stress concentration at the point A, suppressing the lowering of sealability due to a reduction in creep of the lip, and increasing the follow-up capability of the lip to the eccentricity of its axis. Indentations are formed on the slidable contact surface (41) of the plate-like lip (4) or/and the anti-slidable contact surface (42) thereof. Indentations (7) are also formed on the sloped slidable contact surface (21) of the inner lip (2) of the seal. Then, the ratio of the portion of each of the slidable contact surfaces where the indentations (7) are formed is ½ or more of each of the surface areas of the slidable contact surfaces (21, 41, 42).

    摘要： 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.
