Abstract
A weather strip allowing the opening and closing operations of the window glass in a door of automobile to be performed is formed by a base portion made of a hard synthetic resin, a support portion made of a soft synthetic resin and a contacting band layer comprising two synthetic resins of different melting points, of which powder or particles of the synthetic resin of a high melting point are mixed with the synthetic resin of a low melting point. The contacting band layers are provided on the portions of the base portion and support portion where the window glass abuts. The contacting band layer is formed by extrusion simultaneously with the extrusion of the base portion and support portion, whereby a rough face is integrally formed on the surface of the contacting band layer.
