Abstract: A weather strip for mounting relative to a door opening in an automobile includes an elongated body including a longitudinal trim portion of a U-shaped cross-section for being fitted on a peripheral flange formed on the periphery of the door opening, a hollow seal portion formed on an outer face of one of opposed arms of the trim portion, and a sealing lip for sealing engagement at its distal edge with a surface defining the door opening. A door of the automobile is adapted to be sealingly engaged at its peripheral edge portion with the seal portion. The strip body includes two straight elements of rubber and a corner element of molded rubber interconnecting the straight elements at their one ends and molded integrally therewith. The sealing lip of the straight element is formed on one end of the one arm of the trim portion.
