An outer sealing strip for windowsills of automobiles comprises a
metal framework and an organic elastic piece. The organic elastic piece is attached onto the surface of the outer sealing strip, the
metal framework and the organic elastic piece extend along the same section to form the outer sealing strip, the cross section of the
metal framework is irregularly inverted-V-shaped, the outer side of an outer automobile edge of the
metal framework is exposed out of a bright surface of the outside of an automobile, most of parts of the organic elastic piece are attached to the surface of the outside of an inner automobile edge of the irregularly inverted-V-shaped
metal framework, protruded lip sheets which extend obliquely upwards are respectively formed on the top, in the middle and at the bottom of the organic elastic piece, so that a first water flowing trough is formed between the top of the organic elastic piece and the middle protruded lip sheet, a second water flowing trough is formed between the middle of the organic elastic piece and the bottom protruded lip sheet, inner automobile sides of the middle of the organic elastic piece and the bottom protruded lip sheet cling to lifting glass of an automobile window during usage, and flocked
layers are arranged on surfaces of the inner automobile sides of the middle of the organic elastic piece and the bottom protruded lip sheet so as to reduce friction resistance between the glass and an
adhesive tape when the glass ascends and descends.
