とした一体型オイルシール。 An integrated oil seal is installed on a housing 1 and a shaft 2 that rotate with each other, and is composed of a sealing element 4 having an oil lip 3 and an auxiliary sealing ring 5; the auxiliary sealing ring 5 is formed into a substantially U-shaped cross section. An extending flange portion 6 facing inward is formed at the outer axial end of the sealing element 4, and the other sealing element 4 is formed into a substantially L-shaped cross section and protrudes diagonally in the axial direction toward the radial portion of the sealing element 4. The oil lip 3 is arranged so that when the oil lip 3 is brought into contact with the radially inner circumferential surface of the auxiliary sealing plate 5, its tip contact portion has a diameter larger than the tip diameter of the extending flange portion 6. Integrated oil seal.
