Claim:
A glass run that is mountable on a frame, wherein the frame has a substantially straight frame body and L-shaped frame corner parts connected to the frame body, the glass run supports a door glass such that the door glass can slide with respect to the glass run, and wherein the glass run comprises: a horizontal extrusion part and vertical extrusion parts, which are mountable, respectively, on the frame body; and corner molding parts having variable cross sections connecting terminal ends of the horizontal extrusion part and the vertical extrusion parts by injection molding, and the corner molding parts are mountable on the frame corner parts, respectively, wherein: the cross section of the horizontal extrusion part, the cross sections of the vertical extrusion parts, and the cross sections of the corner molding parts are generally U-shaped but are different from one another, and each of the horizontal extrusion part, the vertical extrusion parts and the corner molding parts includes a pair of opposed sidewalls and a bottom, which form the U-shaped cross sections and receive the door glass; horizontal parts of the corner molding parts are larger than vertical parts of the corner molding parts; a thickness of the bottom of the horizontal parts of the corner molding parts over the entire area of the horizontal parts of the corner parts is larger than that of the horizontal extrusion part and the vertical extrusion parts; each of the horizontal extrusion part, the vertical extrusion parts and the corner molding parts has engaging lips for engaging the frame; and said engaging lips of the corner molding parts are located at opposite sides, respectively, of said bottom and are relatively thick in a width direction of said bottom so that said engaging lips are supported by said bottom, whereby a fitting force that occurs when said engaging lips engage the frame is high.
