2. Description of the Related Art For example, a molding is attached to a body outer plate of an automobile for the purpose of decoration, protection of the body, and the like.
This molding is usually formed of a band-shaped molded product made of a synthetic resin, and is formed by means such as extrusion molding, injection molding, and blow molding. As the prior art of the molding by blow molding, Japanese Utility Model Publication No. Sho 63-22123 and Japanese Patent Application Laid-Open No. 60-143159 are cited, and the former is intended to reduce the weight of the molding and make it easier to mount it on a vehicle body. The gist of the latter is that clips can be assembled. These moldings have been improved in consideration of assembly, simplification of the structure, etc., and they have been designed in terms of design, such as decoration and color, as well as weather resistance, impact resistance, and manufacturing costs. It is not an improvement in consideration of.

[0003] In other words, the decorative molding described in Japanese Utility Model Publication No. 63-22123 is one in which clips are fastened at the same time as blow molding, but the decorative surface side of the molding body has a design property such as color. There is no consideration for the material used, and it seems that the durability is unknown. Also, the molding described in Japanese Patent Application Laid-Open No. 60-143159 has a blow molded part on the decorative surface side which is too simple and has no decorative property.
In addition, there is no description about the material, durability, and the like as described above.

[0004] FIG. 7 is a cross-sectional view of a molding formed by conventional extrusion molding. A core material coating layer 22 is applied to the entire surface of a core material 21. An outer layer 23 is coated on the decorative surface side. Since the layer thicknesses of the core material coating layer 22 and the outer layer 23 are constant along the longitudinal direction of the molding, the synthetic color feeling due to the unique colors of the layers 22, 23 appearing on the decorative surface side is as follows: It is the same in all parts along the longitudinal direction of the molding, and there is a problem of lacking in designability regarding color.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a unique color appearance on the surface of a molding body to enhance its design.

[0006]

Means for Solving the Problems In order to solve this problem, a means adopted in the present invention is to form a molding body with a plurality of layers, and to reduce the total thickness of the plurality of layers along the longitudinal direction thereof. Keeping it constant, changing only the layer thickness of each layer,
That is, at least the outermost layer on the decorative surface side is formed of a material having a light transmissive property that does not become opaque.

[0007]

Since the total thickness of the plurality of layers constituting the molding body is kept substantially constant along the longitudinal direction and only the thickness of each layer is changed, the color of each layer is changed. The synthesized colors differ in all parts along the longitudinal direction of the molding body, and the different synthesized colors appear on the decorative surface via the outermost layer having light transmittance.
