ABSTRACT:
In the end portion of a weather strip, the projecting base end portion of a hollow seal portion is left as a first uncut-off portion, whereas the main portion of the hollow seal portion is cut off. The thus treated end portion is set in a split mold. In this setting, a cooling mold is brought into contact with a decorative high molecular layer. Also, the first uncut-off portion is pushed down in a direction away from the decorative high molecular layer is thereby pressed against the outer surface of the side wall of a trim portion. Also, a first middle mold is disposed opposed to the outer surface of the side wall to thereby form a cavity, while the cavity and decorative high molecular layer are separated from each other through the first uncut-off portion. Molding material is injected into the cavity to thereby form a mold forming portion.
