ABSTRACT:
The present invention is directed to a door weather strip in which the corner portions thereof are integrally formed with straight portions thereof. In order to obtain a predetermined sealing interference, the cross sectional shape of the corner portions of hollow sealing portion and the lip seal of the weather strip is arranged to be longer than that in the straight portion. Alternatively, the sealing portion is raised as to have a predetermined shape when the corners are formed. Said formed shapes are solidified by vulcanization after the weather strip has been plastically deformed before the vulcanization.
