2. Description of the Related Art As shown in FIG. 5, for the purpose of reducing the wind resistance during traveling and improving the stability of a vehicle body, there are several types of automobiles.
A front spoiler 40 may be provided at a lower part of the front of the vehicle body C. The front spoiler 40 has a fog lamp with a fog lamp 50 on the front and a fog lamp-less specification even if the front spoiler 40 has the same external shape attached to the same vehicle type. Is appropriately selected.

Conventionally, the front spoiler 40 is formed of a plastic molded product because of its lightness and reduction of damage at the time of contact with other objects. The front spoiler 40 is divided into a type having a fog lamp and a type without a fog lamp by injection molding. Have been. In the case of the specification having a fog lamp, the opening 41 for mounting the fog lamp is formed, while in the case of the specification having no fog lamp, the opening 41 is not formed. For this reason, conventionally, two types of injection molds are required in order to cope with the specification with fog lamps and the specification without fog lamps, and the equipment cost is high and it is not economical.

[0004] The following method can be considered as a method of using one type of the injection mold, but all of them have problems and are not practical.

[0005] One of the methods is a method in which an injection mold having a fog lamp is used for both specifications. That is, an opening 41 for mounting a fog lamp formed in a molded product.
Is covered with a decorative member (not shown) to make it a specification without fog lamps.
The fog lamp 50 is mounted on the device 1. In this method, since the decorative member must be fixed to the fog lamp mounting opening 41, not only the fixing means is complicated, but also most of the back surface of the decorative member is not supported by the presence of the fog lamp mounting opening 41. In addition, there is a problem that the decorative member is easily rattled.

[0006] Another method is to use an injection mold having no fog lamp and serve both specifications. That is, as shown in FIG. 6, a fog lamp-equipped front spoiler 40 </ b> A made of an injection-molded product is cut off a fog lamp mounting scheduled portion 41 </ b> A by post-processing to form the opening 41, thereby obtaining a fog lamp-equipped specification. In the case of the specification without the fog lamp, the fog lamp mounting scheduled portion 41A is left without being cut off. However, in this method, in order to easily cut off the fog lamp mounting portion 41A, a thin portion 42 is formed around the fog lamp mounting portion 41A at the time of injection molding.
When it is attempted to form a thin film, it is difficult to fill the thin portion 42 with plastic, and a problem arises that molding failure occurs.

[0007]
