Thus, this invention uses a wiring harness from the engine room and instrument panel, a roof side inner panel and a quarter panel for a rear combination lamp such as a stop lamp and a turning signal lamp provided at the rear of a luggage room of a sedan type car. It is a device for an insertion path structure that is designed to pass between
In particular, other insertion holes formed in the roof side inner brace are passed through the insertion holes formed in the roof side inner panel immediately before the package tray bracket without damaging the mounting structure of the package tray bracket to the roof side inner panel. A wire harness is inserted between the roof side inner panel and the quarter panel through the through hole of the roof side inner brace to bypass the package tray bracket to avoid interference with luggage in the luggage room. The invention relates to a wire harness insertion path structure for an automobile.

<Prior Art> As is well known, automobiles are equipped with many electric instruments, and a wire harness from a battery, which is generally installed in the engine room, is passed through the instrument panels in the driver's seat to a predetermined position ( It is routed in parallel by some designs).

Thus, for example, in a car such as a sedan type passenger car, wiring of a wiring harness for a so-called rear combination lamp such as a stop lamp and a turning signal lamp is carried out through a driver seat, a rear seat or a luggage room. Due to the structure that must pass through, there were various design problems in the connection with these structural parts.

That is, in the conventional mode in passenger cars shown in FIG. 5 and below, a notch-shaped insertion hole 3 is formed in a roof side inner panel 1 forming a rear seat and a package tray bracket 2 joined to the roof side inner panel 1. , The roof side inner panel 1 beyond the rear wheel house inner panel 4, and the roof side inner brace 5 by-passing through the insertion hole 3 and the other insertion hole 6 formed in the roof side inner panel 1. As described above, the wire harness insertion path 8 is formed between the roof side inner panel 1 and the quarter panel 7 to reach the rear combination lamp (not shown).

<Problems to be Solved by the Invention> However, in the insertion path 8 of the wire harness of the conventional mode, the insertion path forming the insertion path 8 from the rear seat to the luggage room is the roof in the package tray bracket 2. Since the insertion hole 3 is formed in a notch shape at the joint with the side inner panel 1, there is a drawback that the strength and rigidity in the upper part of the rear wheel house inner panel 4 may be insufficient, and the momentum roof side inner panel. However, there is a problem that it also affects the reduction of the rigidity of the connecting portion with the package tray bracket of No. 1.

Further, as shown in FIG. 6, the insertion path 8 formed by the insertion path through the insertion hole 3 has more or less in the luggage room, and there is a disadvantage that it interferes with the stored luggage.
Providing a shield panel or the like to cover the luggage room has the disadvantage of reducing the internal volume of the luggage room to some extent.

Further, in a vehicle type in which the trunk lid and the like are frequently opened and closed, there is a problem that the insertion path of the wire harness that partially passes through the luggage room is visually unrecognizable.

The purpose of this invention is to solve the problem of the insertion passage of the wiring harness wiring for the rear combination lamp in the automobile such as the sedan type passenger car based on the above-mentioned conventional technique, and to reduce the strength of the package tray bracket. Rear wheel house Inner panel suppresses lowering of rigidity, avoids interference with luggage in the luggage room, and does not spoil the appearance. It is intended to provide a wire harness insertion route structure for an automobile.

<Means for Solving the Problem> In order to solve the above-mentioned problems, the structure of the present invention, which is based on the above-mentioned utility model registration claim, is provided between the roof side inner panel and the quarter panel of an automobile. In the insertion path structure of the wire harness leading to the street rear combination lamp, an insertion hole is provided in the flat part of the roof side inner panel in the front part of the package tray bracket, and the roof side inner brace joined to the roof side inner panel is roofed. Another through hole corresponding to the through hole of the side inner panel is provided, and the through hole of the roof side inner panel, the through hole of the roof side panel inner brace, and the insertion passage formed between the roof side inner panel and the quarter panel. With the technical measures that were made to connect and form is there.

<Action> Thus, the battery harness in the engine room, the instrument panel switch, the passenger compartment, the luggage room, the wire harness that connects to the rear combination lamps, and the rear wheel house inner panel in the rear seat are passed. Just before the package tray bracket, through the insertion hole formed in the flat surface of the roof side inner panel, and further through another corresponding insertion hole formed in the roof side inner brace joined to the roof side inner panel. Then, the roof side inner panel and the quarter panel are connected to each other to form an insertion path to reach the rear combination lamp and the like, thereby lowering the strength of the upper portion of the rear wheel house inner panel. In the luggage room without This avoids interference with the stored luggage and prevents the appearance of the luggage compartment from being visually impaired when the luggage compartment lid is opened and closed.

<Embodiment> An embodiment of the present invention will be described below with reference to FIGS. It should be noted that the same reference numerals will be used to describe the same portions as those in FIGS.

The mode shown in FIG. 1 shows the same part as the conventional mode of the passenger car shown in FIG. 5, and the insertion path 8 ′ for the rear combination lamp of the wire harness is bypassed without penetrating the package tray bracket 2. As shown in FIG. 4, after passing through the rear wheel house inner panel 4 of the rear seat, and immediately before the package tray bracket 2, through the insertion hole 9 formed in the flat surface portion of the roof side inner panel 1. , An insertion hole 10 formed in the roof side inner brace 5 corresponding to the insertion hole 9
As shown in FIG. 2, between the roof side inner panel 1 and the quarter panel 7, passing through an insertion passage formed between
An insertion path 8'passing over the rear wheel house inner panel 11 and reaching a rear combination lamp (not shown) is formed.

Therefore, as compared with the conventional embodiment shown in FIG. 7, the insertion path 8'in FIG.
It bypasses this without passing through, and therefore the roof tray inner panel 1 is attached to the package tray bracket 2.
In connection with the above, the insertion hole 3 as shown in FIG. 5 is not provided, and as long as that is the case, the strength retains the strength as designed at the time of joining.

By providing the through hole 9 in the flat surface portion of the roof side inner panel 1, the joint strength between the roof side inner brace 5 and the package tray bracket 2 is not affected at all, and the input from the suspension tower is effectively applied to the package. It is transmitted to the tray bracket 2.

Since the roof side inner panel 1 has a vertical cross section formed by the roof side inner brace 5 and the suspension tower, its rigidity is sufficiently high, and the through hole 9 is formed in the flat surface portion of the roof side inner panel 1. However, its rigidity has little effect.

In the above configuration, to connect the wire harness from the battery in the engine room (not shown) through the switch of the instrument panel to the rear combination lamp provided at the rear of the luggage room, as described above,
