Abstract
Abstract A weather-strip for an automobile door adapted to be mounted on the edge of the door and closely contact with a body of the automobile when the door is closed, thereby preventing any foreign matter from entering into the automobile. The weather-strip comprises a base section which is to be mounted on the edge of the door and a hollow seal section integrally formed with the base section. The hollow seal section comprises a first wall having a protrusion formed at the upper end thereof, a second wall and a mountain-shaped top wall having a ridge formed therein. The hollow seal section is adapted to collapse when the door is closed, thus providing a positive sealing effect for the automobile door.
