Automobile weather strip

A roof-side weather strip is provided to be attached along a front pillar of a motor vehicle. The weather strip has a base portion adapted to be engaged with the front pillar, and a tubular sealing portion projecting from a front end part of the base portion for closing a gap between the front pillar and a front end edge of the door frame. A rib-shaped projection is formed integrally with a bottom of the tubular sealing portion so as to project within the tubular sealing portion. In the lower end portion of the roof-side weather strip, the seal wall of the sealing portion is bonded to a top end of the rib-shaped projection so that the seal wall has a reduced height relative to that of the remaining portions thereof, and has a configuration conforming to the approaching track of the front end edge of the door frame when a door of the vehicle is closed.
