<P>PROBLEM TO BE SOLVED: To provide a glass run for improving installation workability to a door sash part, while reducing cost by using a relatively inexpensive thermoplastic resin as a material of a cross-sectional substantially channel-shaped base part. <P>SOLUTION: While forming the cross-sectional substantially channel-shaped base part 4 of a foaming body of polypropylene, a seal lip 5 projected from its base part 4 is formed of olefine-based thermoplastic elastomer. Thus, while adopting the relatively inexpensive polypropylene as the material of the base part 4, curving-easiness is provided by using its polypropylene as the foaming body, and the installation workability to the door sash part is improved. <P>COPYRIGHT: (C)2011,JPO&INPIT |
