    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： There is provided a plunger seal (1) for a fuel injection pump for a direct-injection gasoline engine, in which, even if a resin material is used for a fuel seal member (12), the plunger seal can be made compact, sealing ability is increased, and assembling man-hours can be reduced, and in which set sealing performance can be achieved when a U-shaped elastic member (33) for applying an energizing force in a diametrical direction is used in a groove (41) formed in the fuel seal member (12). The resin fuel seal member (12) and an oil seal member (13) are assembled to form one seal system. Further, when the U-shaped elastic member (33) is installed in the groove (41), an axial position (L1) of an end surface (44a) at the side opposite to the sealed object of a fixing collar (44) formed on an inner peripheral surface of the groove (41) is positioned at the side (B) opposite to the sealed object than the axial position (L2) of a leading end portion (15b) of a seal lip (15) of the fuel seal member (12).
