Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carpet on a lower part of a vehicle body when carpets are laid on upper surfaces of a floor panel and a floor side member constituting a lower part of the vehicle body. Mounting structure. 2. Description of the Related Art A conventional carpet mounting structure for a car body floor is disclosed in Japanese Utility Model Laid-Open Publication No. Hei 2-16334, particularly as shown in FIG. [0003] According to this, the lower part of the body of an automobile is provided with a floor panel, floor side members attached to each side edge of the floor panel, and side sills provided outside the floor side members. I have. The upper edges of the floor side members and the side sills corresponding to each other and the lower edges thereof are connected to each other. A carpet is laid on each of the upper surfaces of the floor panel and each of the floor side members. The side edges of the carpet are superimposed on a joint formed by joining the upper edges of the floor side member and the side sill, and externally fitted to these joints so as to integrally sandwich the joint with the side edge of the carpet. Opening trim is provided. [0004] The outer trim of the opening trim attaches the side edge of the carpet to the joint, that is, attaches the carpet to the lower part of the vehicle body. [0005] By the way, in the above-mentioned conventional structure, an opening trim is externally fitted to the connecting portion and the side edge of the carpet so as to sandwich the same integrally. Because it is soft,
When the opening trim is fitted to the outside, the side edge of the carpet is easily bent by receiving an external force from the opening trim, so that the work of attaching the side edge of the carpet to the connection portion is complicated. Therefore, it is conceivable to attach a rigid elongate body made of resin or the like along the side edge of the carpet to improve the rigidity of the side edge of the carpet. However, this makes it difficult for the side edge of the carpet to bend, making it difficult to accurately align the side edge with the combined body. In this case, it becomes difficult for the opening trim to be fitted to the side edges of the carpet and the combined body, and there is a problem that the ease of attaching the side edges of the carpet is not sufficiently improved. In addition, when the rigid long body is made of resin, there is a problem that the molding cost of the long body is increased, and thus the cost of the carpet mounting structure is increased. SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to facilitate the work of attaching a side edge of a carpet to a lower part of a vehicle body. It is another object of the present invention to reduce the cost of the carpet mounting structure.
