Abstract
A lip seal device for a rotary shaft in which an annular metal casing has a cross section almost in a box shape except for a radially and axially inward gap. A seal member fills most of the box. A spacer and a radially outer portion of a lip seal, contacting the rotary shaft at its inner portion, are sandwiched in the gap between a radial wall of the casing on one side and the seal member and an end of the inner axial wall of the casing.
