摘要： A seal lip of an oil seal is in slidable contact with a peripheral surface of a shaft. A lubricating oil supply section for collecting adhered oil and dropping it on the shaft is provided at a forward end portion of an installation section. The lubricating oil supply section has projections formed on the inner peripheral surface of the installation section to collect oil on the surface thereof. The surface of each projection has a recess for temporarily accumulating oil. Guidance projections, or a slope for collecting the oil, and dams are formed on a forward end face of the installation section to block the oil flowing down along the circumferential direction on the forward end face and guides the oil toward each projection.

摘要： This invention provides an oil seal that can maintain an excellent friction reduction function over a long period of time, has excellent abrasion resistance, and further has excellent sealing properties. The oil seal comprises a seal lip (4) formed of a rubber-like elastic material comprising a lip edge part (9) and an air-side slope (8) and a sealing fluid-side slope (10) provided on both sides of the lip edge part (9). The air-side slope (8) has a coating film (14) on its surface. In the lip edge part (9) in its portion in contact with a shaft (13), a sealing fluid-side rubber part (2′) and an air-side coating film (14) are simultaneously brought into contact with the shaft (13). The coating film (14) is preferably formed of a coating agent comprising a fluororesin, a polyethylene resin, an isocyanate-modified polybutadiene resin, and a solvent.
