ことが一般的に知られている。2. Description of the Related Art Conventionally, a weather strip for sealing a door glass of a vehicle of this kind repeats up and down a number of times, and it is necessary to smoothly open and close an up and down window glass. Further, it is necessary to maintain hermeticity, and further, it is necessary to have an aesthetic appearance over a long period of time. Therefore, this type of weather strip is made of a synthetic rubber or a thermoplastic elastomer made of a material capable of reducing the weight of a press-contact portion to which the elevating door glass is pressed, which has flexibility, elasticity and cushioning property. Fine hair such as nylon or polyester is implanted on the surface that comes into contact with the glass, or a coating of a dissolved synthetic resin such as urethane or nylon is applied.However, the surface of other weather strip is not subjected to any surface treatment. Is generally known to be used without being implemented.

る便利な効果もある。As described above, according to the weather strip of the present invention, the constituent material of the weather strip is a thermoplastic elastomer made of a polyolefin resin, and the surface exposed to the outside has excellent abrasion resistance and chemical resistance. By molding the polyolefin resin into a thin film with a thickness of 0.05 mm or less, the surface is very good in appearance and prevents scratches, and no cuts are made.
It has the advantage of maintaining the luster for a long period of time and improving the quality, and has the effect of preventing the solvent such as aromatic kerosene and white gasoline from being attacked by the chemicals and roughening the skin. Also,
Since the thermoplastic elastomer of the weatherstrip body and the polyolefin resin forming the thin film are mutually compatible, they are simultaneously extruded, so that the whole is integrally fused by heat and pressure during the extrusion. There is also an effect of toughening. Then, for the two extruders, the extruder for the weather strip and the extruders for forming the thin film, the synthetic resin material can be appropriately selected. In addition, the material extruded from each extruder was inserted through one mold die and pressure-bonded, so it was significantly tougher than the one with the conventional synthetic resin paint and flocking attached, and the thin film was strongly There is an effect of being integrated. Further, there is also a convenient effect that the thickness of the thin film can be freely adjusted to an appropriate thickness of 0.05 mm or less.
