An annular elastic gasket adapted to be disposed between an insertion hole formed in a housing and a cylindrical body which is inserted into the housing via the insertion hole in such a manner that the annular elastic gasket elastically contacts an inner surface of the insertion hole and an outer circumferential surface of the cylindrical body. The annular elastic gasket comprises a hollow cylindrical gasket base body comprised of a molded body made of an elastic material, to be compressedly fitted and retained in the insertion hole, an annular seal lip portion extending in the centripetal direction from the gasket base body and an elastic extending portion which constitutes an extending base portion at an end of a tip side portion of the annular seal lip portion, being bent in such a manner that the end directs in the centripetal direction. The elastic extending portion elastically expands in the diametrical direction together with the tip side portion when the cylindrical body is inserted into the insertion hole, thereby the elastic extending portion elastically contacts the outer circumferential surface of the cylindrical body while maintaining elastic restoring force in the contracting direction.
An annular elastic gasket adapted to be disposed between an insertion hole formed in a housing and a cylindrical body which is inserted into said housing via said insertion hole in such a manner that said annular elastic gasket elastically contacts an inner surface of said insertion hole and an outer circumferential surface of said cylindrical body, said annular elastic gasket comprising:
