Sealing device for relatively rotating machine components e.g. in electric handtool, has sealing edge raised out of sealing position during fitting of sealing device by integral projection

摘要

The sealing device (10) has at least one sealing ring (20) with a sealing edge (23) pressed against an inner machine component (15) in the operative position of the sealing device and raised from the machine component during fitting by an integral lifting projection (27), which locates in a recess (29) in the outside of the machine component when the sealing device is in position.
