Abstract

PROBLEM TO BE SOLVED: To improve the appearance in an engine room by arranging at least one of pipes and harnesses of an engine, which is mounted in an engine room, in a space having a closed cross section of a car body structural member horizontally arranged in the engine room. SOLUTION: Pipes 22 in an engine room 12 are arranged in a space 24 having a closed cross section of a strut bar 10 as a car body structural member, which is horizontally arranged in the engine room 12. The strut bar 10 is provided with insertion holes, in which each pipe 22 having a closed cross section is inserted, in both side in the cross direction of a vehicle. With this wiring structure inside of an engine room, since the pipes 22 of the engine are arranged in the clearance 24 having a closed cross section of the strut bar 10 as a car body structural member, which is horizontally arranged in the engine room 12, the whole surface of the pipe 22 can be covered with the strut bar 10. Appearance in the engine room 12 can be thereby improved.

2. Description of the Related Art Pipes and harnesses connected to an engine are arranged in an engine room of a vehicle. As a conventional wiring structure in the engine room of a vehicle, as shown in FIG.
There is one shown in FIG. In FIG. 5, 102 is a vehicle, 104 is a frame, 106 is a side member, 108
Is a cross member, and 110 is a strut bar.

The frame 104 of the vehicle 102 is the vehicle 10
2, the side members 106 respectively arranged on both sides in the width direction.
Are connected by a cross member 108 below the engine room 112 in front of the vehicle 102. Note that FIG.
The side member 1 on one side in the width direction of the vehicle 102.
06 and the cross member 108 are illustrated.

On the frame 104, an engine (not shown) is mounted in an engine room 112 in front of the vehicle 102, and it is positioned under the floor behind the vehicle 102 and the fuel tank 11 is installed.
It is equipped with 4. Engine room 112 of vehicle 102
The strut bar 110, which connects the left and right strut mechanisms 116 of the front wheel suspension device, is horizontally provided above.

In the engine room 112, as shown in FIGS. 5 to 7, a fuel supply pipe 118 for supplying the fuel from the fuel tank 114 to the engine and an excess fuel are supplied to the fuel tank 114.
Fuel pipes such as fuel return pipe 120
22 are arranged, and as shown in FIGS. 8 to 10, harnesses 124 for an electric system are arranged.

Pipes 122 in the engine room 112
Clamps the one side 126 of the cross member 108 to the clamp 12
8 is fixed and provided, and as shown in FIG. 7, a heat-resistant / stepping-proof protective material 130 such as foamed rubber is provided so as to be encapsulated. The harnesses 124 in the engine room 112 are fixedly provided on one side surface 132 of the strut bar 110 by a clamp 134, and as shown in FIG. 10, are provided with a heat-resistant and stepping-proof protective material 136 such as a corrugated tube. .

In FIG. 6, reference numeral 138 is a fuel filter. The fuel filter 138 is attached to the strut bar 110 on the other side in the width direction of the vehicle 102 and is interposed in the fuel supply pipe 118.

An example of such a vehicle-installed structure in the engine room is disclosed in Japanese Patent Laid-Open No. 62-99265.

Is fixed to the strut bar 110 in the engine room 112 by the clamp 134, the assembly work is troublesome and the number of parts increases.

In the conventional engine room wiring structure, the pipes 122 are arranged along the cross member 108 from one side in the width direction of the vehicle 102 to the other side.
There is a disadvantage that the shape becomes complicated and a large storage space is required.

Further, in the conventional engine room wiring structure, since the harnesses 124 are fixed to the one side surface 132 of the strut bar 110 in the engine room 112 by the clamps 134, they are exposed in the engine room 112. Therefore, there is a disadvantage that it is disadvantageous in appearance.

Furthermore, in the conventional engine room wiring structure, the pipes 122 are fixed to the one side surface 126 of the cross member 108, and the harnesses 124 are attached to the strut bar 1.
Since it is fixed to one side surface 132 of FIG.
As shown in, the entire surface cannot be hidden, and a part of it is exposed to the outside.
In addition to the inconvenience that 6 cannot be abolished, it is necessary to provide a protective cover 140 as shown in FIG.

[0013]

Therefore, in order to eliminate the above-mentioned inconvenience, the present invention provides an engine mounted in the engine room in a closed cross-sectional space of a vehicle body component member that is horizontally installed in the engine room of the vehicle. At least one of pipes and harnesses is provided.

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION In the engine room wiring structure of the present invention, at least one of engine pipes and harnesses is arranged in a closed cross-sectional space of a vehicle body component member that is laid horizontally in the engine room. , The entire surface of the pipes and harnesses can be covered, the pipes and harnesses are not exposed to the outside, and the clamps for fixing and the heat-resistant / stepping-proof protective material can be abolished. It is possible to eliminate the work of assembling clamps and heat-resistant and stepping-proof protective materials.
