As shown in FIG. 10, the rear vertical side mold 35 is formed of an upper mold 40, a lower mold 41, an intermediate plate 42, a first core mold 43, and a second core mold 44. The lower part of the rear vertical side 10c is formed.

  Since the division bar 3 is integrally embedded in the lower portion of the rear vertical side portion 10 c in the same manner as the upper portion, the division bar 3 is attached to the cavity 46. The division bar 3 is integrally and continuously attached from the above-described quarter weather strip 20. The division bar 3 is divided into two in the longitudinal direction like the upper part, and is composed of an outer division bar 3a and an inner division bar 3b.

  The division bar 3 may be formed in close contact with the vehicle outer side wall 11, the vehicle inner side wall 12, and the bottom wall 13 of the glass run 10, or may be embedded inside. Similar to the upper part, the outer division bar 3a and the inner division bar 3b are opened and formed in a cross-sectional C shape at the time of molding, and are closed in a substantially U-shaped cross section at the time of mounting.

As the molding material for the glass run 10 and the quarter weather strip 20, synthetic rubber, thermoplastic elastomer, and soft synthetic resin are used. For example, EPDM rubber is used for synthetic rubber, and olefin elastomer and soft synthetic resin is used for thermoplastic elastomer. Then, soft vinyl chloride or the like is used.
In the case of synthetic rubber, the molding material is poured into a mold and then heated and vulcanized. In the case of a thermoplastic elastomer or a soft synthetic resin, it is cooled and solidified.
