Further , the long resin molded article for a vehicle according to the present invention comprises:
In addition to a molded article made of one type of synthetic resin, a sandwich molded article composed of a skin material and a core material injected therein can also be used. In particular, in the case of a long resin molded product such as an over fender or a rock molding, the first piece and the second piece are sandwich molded products in order to satisfy the flexibility at the time of mounting and the rigidity after mounting. Is preferred.

[0018]

In the present invention, a rib gap is provided between the plate-like rib and the second piece. Therefore, there is no possibility that thermal deformation occurs at the time of molding the resin molded product. That is, the resin molded article is molded by, for example, injecting a molten synthetic resin into a mold by an injection molding method. Then, the resin molded product is taken out of the molding die before being sufficiently cooled, and is allowed to cool outside the molding die in order to improve productivity.

On the other hand, when the first piece and the second piece are connected by the mounting portion and the plate-like rib as in the conventional case, the first piece and the second piece are pulled by the above during the cooling. compete. Or they repel each other in some places. Therefore, the resin molded product undergoes thermal deformation. On the other hand, in the present invention, since the rib gap is provided between the plate-shaped rib and the second piece, the first piece and the second piece may be pulled and rebounded as in the conventional example. Absent. Therefore, no thermal deformation occurs and the appearance of the design surface is excellent.
