In providing such a rainwater receiving groove, a concave groove is formed in a decorative portion of a molding body made of an elastic material such as synthetic resin or rubber so as to extend along the side edge of the window glass.

[0005]

[Problems to be Solved by the Invention] However, in conventional wind moldings, as mentioned above, the entire decorative part having the rainwater receiving groove is made of an elastic material, so the groove formation area tends to be damaged, especially in high-temperature environments. It is easily deformed, and there is a risk that the rainwater guide function and appearance may be damaged by mischief such as getting your finger on it.

[0006] Japanese Patent Application Laid-Open No. 62-283017 discloses a wind molding in which a core material is embedded in a decorative part, and the decorative part is reinforced with rainwater receiving grooves. However, in this case, the core material is provided over the entire length of the molding, so that the shape of the molding itself is maintained in a shape that follows the peripheral shape of the window glass. For this reason, there are problems in that it is difficult to attach the molding to an automobile, a large mold is required for molding, and a large space is also required for storing and transporting the molding.

Therefore, the present invention aims to provide a decorative part having a rainwater receiving groove with a certain level of strength while also improving moldability, wearability, and
The purpose of the present invention is to provide an automotive window molding with excellent storage and transportability.

[0008]
