摘要：A rotary shaft seal comprising one member (1) with an annular channel (5) to
receive a radial edge of an annular sealing element (4), and a radially extending lip
portion (6) that forms one side of the channel (5), and is crimped axially inwards to grip
the sealing element (4), said lip portion (6) being formed with a plurality of notches (7)
spaced around its circumference so as to define a serrated edge which grips the sealing
element (4) when the lip (6) is crimped inwards. The notches (7) enhance the grip of the
lip (6) on the sealing element (4) to resist rotational forces. The notches (7) may be
formed by grooves in a radial face (12) of said lip portion (6) that forms said one side of
the channel (5), or in an axially extending face of the lip portion (6) so as to open onto
said one side (12) of the channel.
