ABSTRACT:
An oil seal disposed between a device having a rotary shaft and the rotary shaft. The oil seal comprises an annular supporting member supported within the fixed structure of the device and an annular elastic sealing member disposed in contact with the outer peripheral surface of the rotary shaft in such a manner as to allow relative sliding rotation therebetween. The annular supporting member has a peripheral supporting portion with a cup-shaped section taken along a plane including the axis of the rotary shaft, and the cup-shaped section opens to the outside of the device in the axial direction thereof. The annular elastic sealing member is fixed to an annular, radially-inwardly projecting portion of the annular supporting member.
