[0002]

2. Description of the Related Art Recently, in order to improve the efficiency of assembling a car, a structure in front of an engine room, which is a "front compartment", is manufactured in advance as a front-end module, and the module is manufactured in a manufacturing line.
A structure for attaching to a vehicle body is adopted (for a similar technique, see Japanese Patent Application Laid-Open No. 7-35255).

[0003] The front-end module is composed of a skeleton frame and peripheral equipment to be assembled thereto. The skeletal frame is a radiator core support, a first cross member, or the like, and is responsible for the strength of the vehicle front. Peripheral equipment refers to radiators and lamps that are “heat exchangers”, and also includes harnesses and pipes associated therewith.

[0004]

However, in such a conventional technique, since the skeletal frame is formed by assembling a plurality of metal parts in a complicated manner, for example, the effect of ventilation to the radiator is reduced. Even if an attempt is made to add a large air guide member surrounding the radiator opening to the skeletal frame in order to increase the height, it is difficult to secure the installation space, and it is also difficult to secure mounting points for other parts. That is, there are few places that can withstand the attachment of the air guide member.

[0005] Further, since the skeleton frame is made of metal, when wiring a harness to the skeleton frame, it is necessary to cover the harness with a tube-shaped protector in order to obtain an electrically disconnected state between the harness and the skeleton frame. Therefore, the work of arranging the harness is troublesome because the protector must be provided.

The present invention has been made by paying attention to such conventional technology, and provides a front end module of a vehicle in which an air guide portion can be easily formed and a harness need not be protected by a protector. It is.
