(S ') is an example where it is attached to the position of the lower edge of the vehicle door (D) similar to that shown in FIG.
(S ') is made of a soft synthetic resin material having a soft feeling with the surface layer (1') as a skin layer, and the core layer (2 ') of the core portion is a low linear expansion synthetic resin having high rigidity. It is made of a hard material. This molding uses a fixed mold for the skin layer and a fixed mold for the core layer and its movable mold, that is, two fixed molds and one movable mold as an injection molding mold to have two cylinders. By attaching to a two-color molding machine and sliding (moving) a movable mold in this two-color molding machine, the whole is integrally molded simultaneously and manufactured. First, after injecting the core layer material into the fixed mold for the core layer and the movable mold, slide the movable mold in the molding machine, replace it with the fixed mold for the skin layer, and injection mold the skin layer. Enables product acquisition in cycles. The attachment (3) shown in Fig. 2 is assembled to the obtained product by attaching it to the attachment portion (2 ") provided on the core layer (2 ') so that it can be easily attached to the vehicle body. ) Prevents dust, rainwater and muddy water from entering the vehicle step (5), ie the door (D).
Ingress of dust and dirty water into the lower vehicle step (5) is
Since the surface layer (1 ') is a skin layer made of a soft material, there are no gaps, and the cushioning property when opening and closing the door (D) is provided, which is convenient.

クル材として活用も容易である。EFFECTS OF THE INVENTION The two-layer resin molding product for a vehicle of the present invention has a soft feeling on the surface by using a synthetic resin hard material for the core layer and a soft synthetic resin material for the skin layer, and has a decorative surface. The material is excellent in rigidity, has high rigidity in the core, and has a low linear expansion.
Further, it is intended to reduce the deformation due to the temperature change of the outside air, and it is much more useful for reducing the weight of the vehicle as compared with the above-mentioned conventional product using a stainless material for the core. In addition, this core part is made of recycled material (particularly for vehicle parts, once used wheel cover,
The use of a bumper or other synthetic resin material has the advantage that it is easy to use because its strength and physical properties are already known for vehicles.) Therefore, it is possible to cope with the recent improvement of resource environmental problems. . Further, according to the manufacturing method of the present invention, since the product can be obtained in a single cycle in a fully automatic manner, the troublesomeness of inserting after the primary molded product is released. It is also possible to utilize the above-mentioned recycled materials, which also contributes to cost reduction. Further, unlike the conventional product, it is not a composite use of a metal material and a synthetic resin material, so that it can be easily used as a recycled material again.
