ABSTRACT:
An oil seal assembly includes an oil seal having a lip contacting the outer peripheral surface of a reciprocating shaft, a holder for holding the oil seal about the shaft, and an annular spring for urging the lip against the outer peripheral surface of the shaft. The lip has a flat surface which is inclined with respect to the outer peripheral surface of the shaft. When the oil seal is mounted on the shaft, the flat surface is brought into surface contact with the outer peripheral surface of the shaft by an urging force applied by the spring.
