Glass run

A glass run of an automobile door, for guiding a door glass in a frame, the glass run comprising:

• a body having a substantially U-shaped cross-section including an outer-cabin side wall, an inner-cabin side wall which is longer than the outer-cabin side wall in cross section and a connecting wall which connects the side walls and forms a channel;
• an outer lip which extends toward an inner-cabin side from an end part of said outer-cabin side wall and is slidably brought into contact with said door glass;
• an inner lip which extends toward an outer-cabin side from a position on an outer-cabin side surface of said inner-cabin side wall and is slidably brought into contact with said door glass, the position being at a distance toward a side of said connecting wall from an end part of said inner-cabin side wall;
• and a holding lip which extends from the end part of said inner-cabin side wall for fastening an inner-cabin side part of said frame together with said inner-cabin side wall and elastically engages an inner-cabin side surface of the inner-cabin side part of said frame, wherein:
• a noise insulation wall protrudes at least on the end part of said inner-cabin side wall or around the end part for closing a concave space between an inner-cabin side surface of said door glass and the inner-cabin side wall;
• and the noise insulation wall is integral with or separate from the glass run.
