2. Description of the Related Art In general, a wire harness used in an electric circuit of an automobile of this type is formed by winding a plurality of required cables into a bundle so that the trunk portions of the cables are bundled and bundled together. The cable is led out to each end and the connection connector is attached to the end. Normally, the trunk portion of each of the cables thus bundled is connected between the frames of the automobile, between the panels, and the vehicle. The cables are arranged in a relatively narrow space such as a shell and fixed appropriately, and then the connection connectors of the cables distributed from the main line portion are connected to the corresponding electrical components. .

On the other hand, in a wire harness in which a plurality of main line parts are bundled, the outer shape of the main line part inevitably swells and becomes large. Therefore, between the frames, between the panels, and the car shell. It is not easy to install the cable in a limited space such as inside, and such a disadvantage becomes more apparent as the number of electric components to be installed increases recently.

Therefore, in order to improve this point, conventionally, as disclosed in, for example, Japanese Patent Application Laid-Open No. 61-51707, as a wire harness device applied to a door device of an automobile, a trunk line of a wire harness is used. There is a structural means for maintaining and holding the part on the mounting plate in a flat shape.
