Abstract

PURPOSE: To improve the sealing quality of the oil seal by providing an inclined stripe having a predetermined angle of inclination by means of the metal die molding techniques and constituted by convexes and concaves of heights about 0.0005W 0.03mm on the side opposite to a sealed fluid of the inner peripheral end of a seal lip of the oil seal.
CONSTITUTION: An oil seal body 1 comprises a reinforcing ring 2, a membrane part 3, a seal lip 4 and a spring 5. The membrane part 3 and seal lip 4 are made of rubber or the like. If necessary, there is attached a film member made of a material including mainly a fluoroplastic to the inner periphery of the seal lip 4. At the inner peripheral end of the seal lip 4, there is provided by means of the metal die molding techniques the inclined stripe having an angle of inclination θ with respect to an inner peripheral end line 6 and constituted by convexes and concaves of heights about 0.0005W0.03mm on the side opposite to the sealed fluid L. Accordingly, the inclined stripe 7 is formed in a substantial screw having an angle of inclination θ. This oil seal is fitted to a scaing 8 for sealing up a shaft 9.
