ABSTRACT:
An improved structure of a weatherstrip member for sealing an end of a pane of window glass applicable to a vehicular door is disclosed wherein a bleed rubber material mixed with a lublicant is used in a pair of seal lips extended from tips of the pair of side wall portions to reduce sliding resistance of the seal lips against side surfaces of the pane of window glass pane, a thicker bottom portion (rib) is provided on a part of the bottom of the weatherstrip member so that when the end of the pane of window glass is inserted in an internal space defined by the weatherstrip member with an offset toward the vehicular outside portion from a center line of a door sash, the thicker portion and a thinner part of the bottom portion of the weatherstrip member on which the top surface of the end of the pane of window glass is touched are contacted with the bottom portion of the door sash. In addition, one of the pair of seal lips extended from the tips of the side wall portions has a bending point deviated toward the vehicular inner side to make the lengthes of both seal lips equal to each other so that when the pane of window glass is inserted as described above and contacted with a portion of the weatherstrip member which is deviated in the vehicular outside direction, the face contact therebetween can be assured.
