[0003]

The manufacturing process of the above-described conventional example will be described.
A, after passing through an assembling process of joining the outer panel 1B and the floor pan 2 by welding, the process proceeds to an outfitting process of sequentially assembling the line holding component 3, the protector 4, the floor carpet 5, and the side sill cover 6. In this outfitting process, it is desirable that the assembling of each component be completed with as simple a task as possible. In the above example, first, the line holding component 3 is fitted into the mounting hole of the inner panel 1A (first procedure), and then the protector 4 is fitted into the mounting hole of the inner panel 1A (second procedure). 4c is fitted to the joint of the side sill 1 (third procedure), the side end 5a of the floor carpet 5 is fitted to the engaging portion 4b of the protector 4 (fourth procedure), and finally the side sill cover 6 is attached to the mounting hole of the outer panel 1B. The work is completed by fitting into (fifth procedure). Therefore, there is a problem that the conventional one requires five procedures for the outfitting process, and the work becomes complicated.

In the above example, in the outfitting process,
The three components of the line holding component 3, the protector 4, and the side sill cover 6 are directly fitted into the side sill 1. Therefore, it is necessary to form three mounting holes in the inner panel 1A or the outer panel 1B of the side sill 1. . The formation of the mounting holes is to be prepared as a preparatory work before the outfitting process. However, if the number of mounting holes is large, the preparation work takes time and the work efficiency is degraded.
Since this mounting hole may cause raindrops or the like to enter the side sill 1, it is desirable to form the mounting hole as small as possible in order to avoid deterioration due to rust.

The present invention has been proposed in order to address such a problem, and the working procedure of the outfitting process can be simplified, and the working efficiency can be improved by reducing the number of mounting holes formed in the side sill. It is another object of the present invention to provide a vehicle side sill peripheral structure capable of preventing deterioration of the side sill.

According to the third aspect of the present invention, based on the premise of the first or second aspect, a positioning projection inserted into a positioning hole formed at a side end of the floor carpet is provided at the holding portion. It is characterized by being formed.

The present invention having the above-described features has the following effects.

According to the first aspect of the present invention, in the side sill peripheral structure, the protector portion for covering the line holding component and the holding portion for holding the side end portion of the floor carpet are formed by a single assembled component. Can be assembled into a unit by previously sandwiching the assembled part with the side end of the floor carpet, and can be assembled in a single operation procedure. Therefore, the assembling work in the outfitting process can be simplified. Also, instead of assembling this assembled part directly to the side sill, it is designed to engage with the line holding part,
The number of mounting holes formed in the side sill can be reduced. Further, since the upper surface of the grip portion is also used as the side sill cover, the number of components can be reduced.

According to the second aspect of the present invention, in addition to the above operation, the front end side of the assembled component is folded back by the self-hinge portion to form a holding portion, and the engaging projection provided on the front end side is provided on the floor carpet. Since the structure engages with the engagement hole formed in the assembled component itself through the opening formed in the side end, the holding portion can be formed by a single component, and the number of components does not increase.

According to the third aspect of the present invention, in addition to the above operations, the holding portion is provided with the positioning projection to be inserted into the positioning hole formed at the side end of the floor carpet. Position regulation can be easily performed.
