Glass run and method for manufacturing the same

A glass run comprising:

• an extrusion portion formed by an extrusion-molding method;
• and
• a molded portion formed by an injection molding method so as to be connected to an end portion of said extrusion portion;
• wherein each of said extrusion portion and said molded portion having a body portion with a substantially U-shape in a cross section, said body portion including a bottom wall being attachable to a sash provided in a vehicle body or a vehicle door, and a pair of side walls extending from said bottom wall, and a pair of seal lips extending toward an inside of said body portion from said pair of side walls respectively for sealing a vehicle interior side and a vehicle exterior side with respect to a glass;
• and
• wherein a sectional shape of said body portion corresponding to said molded portion is not substantially changed before and after said glass run is attached to said sash.

A method for manufacturing a glass run comprising a body portion including a bottom wall being attachable to a sash provided in a vehicle body or a vehicle door and a pair of side walls extending from said bottom wall, and a pair of seal lips extending toward an inside of said body portion from said pair of side walls respectively for sealing a vehicle interior side and a vehicle exterior side with respect to a glass;

• said method comprising steps of:
• extrusion-molding an extrusion portion having said pair of side walls, where said pair of side walls expanded with respect to said bottom wall has a substantially longitudinally equal sectional shape;
• and
• injection-molding a molded portion by injecting a molding material into a cavity while setting an end portion of said extrusion portion in a mold, so that said molded portion is connected to said end portion of said extrusion portion;
• wherein a portion of said cavity corresponding to said body portion has a substantially unexpanded U-shape in a cross section.
