An inner side cover lip 14 that covers the inner side wall 6b of the channel 6 and the inner edge of the outer surface of the inner panel 9 is integrally formed. The surfaces of the seal lips 12, 12 and the base of the glass run main body 11 are subjected to a lubrication treatment such as application of urethane or silicone resin in order to enhance the slidability with the door glass 8. .

In FIG. 1 and FIG. 2, the hatched portions indicate the molded portions, and the other portions indicate the extruded portions. As is well known, the molding portion is formed and connected by setting the end of the extrusion molding portion in a mold (not shown) and filling the cavity of the mold with a molding material. Since it is difficult to apply the lubrication treatment to the molded part, the extruded part is made as long as possible, and the lubrication treatment part is extended to be used effectively. The molding material of each part is EPDM solid rubber (ethylene propylene
Diene copolymer), but also, for example, PVC (polyvinyl chloride), TPE (thermoplastic elastomer), T
PO (olefin-based thermoplastic elastomer) and the like can also be used.

The outer cover lip 13 of the extruded portion is cut slightly above the door belt line 3 at a position slightly above the door belt line 3, and the cut end of the outer cover lip 13 has a lower portion of the outer panel 5 and a door belt. A curved molded cover lip 15 covering the inner edge of the outer surface of the corner with the end of the line 3 is connected by molding. The weather strip 70 attached to the door belt line 3 is connected to the tip of the molded cover lip 15.

On the inner surface of the molded cover lip 15 and on the side closer to the connection with the glass run body 11, a positioning notch for engaging with the positioning notch 7 of the outer panel 5 and the outer side wall 6a of the channel 6 is provided. The rib 16 is integrally formed so as to protrude by molding the cover lip 15. The positioning rib 16 is formed in a rectangular parallelepiped shape according to the shape of the positioning notch 7, and its protruding end surface is naturally vulcanized and bonded to the outer surface of the glass run main body 11 (extruded portion) during the molding. ing. FIG. 5 is a rear view showing the rear surface of the molded cover lip 15 with the vulcanized glass run main body 11 peeled off, and the hatched portion in FIG. 5 shows the peeled surface.
