DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric wire fixing structure for fixing a plurality of electric wires along, for example, an automobile body.

[0002]

2. Description of the Related Art An electric wire fixing structure 30 shown in FIG. It has a fixing member 35 in the shape of a circle. This wire fixing structure 30
Each of the insertion portions 34 is inserted into a pair of through holes 36 formed in the vehicle body 31 in a state where the electric wires 32 are interposed between the surface 31A of the vehicle body 31 and the holding portion 33. With
It is bent along the back surface 31B of the vehicle body 31 (see the arrow A in FIG. 3B).

[0003]

By the way, in the above-described wire fixing structure 30, when each insertion portion 34 is bent,
The fixed member 35 tends to move such that the holding portion 33 is separated from the surface 31A of the vehicle body 31 by the component force of the bending force (FIG. 3).
(B) See middle arrow B). Therefore, this wire fixing structure 30
The problem is that the distance between the surface 31A of the vehicle body 31 and the holding portion 33 becomes unnecessarily large and a gap 37 is generated (see FIG. 3C), whereby the electric wires 32 cannot be securely fixed. . The present invention has been made in view of the above-described problems, and an object of the present invention is to provide an electric wire fixing structure capable of securely fixing an electric wire along a body of an automobile, for example.

[0004]

An object of the present invention is to fix a wire having a substantially U-shaped cross section in which insertion portions are connected to both ends of a holding portion in order to fix an electric wire along the surface of a plate member. A member, and in a state where the electric wire is interposed between the surface of the plate member and the holding portion, the insertion portions are respectively inserted into a pair of through holes formed in the plate member. A wire fixing structure that is bent along the back surface of the plate member, having a projection formed at a bending fulcrum of the insertion portion, wherein the projection protrudes toward a bending side of the insertion portion. The problem can be solved by the electric wire fixing structure characterized in that

The fixing member may be formed by bending a metal plate, or may be formed by bending a metal bar. On the other hand, as the projection, a structure in which a predetermined position of the insertion portion is formed in a substantially C shape like a snap pin, or a structure in which the insertion portion is bent in a substantially crank shape can be adopted. Such a protrusion may be formed on one or both of the insertion portions connected to both ends of the holding portion.

[0006] In the electric wire fixing structure thus configured, since the projection protrudes from the bending fulcrum of the insertion portion on the bending side, when the insertion portion is bent along the back surface of the plate member such as the vehicle body, the plate member is bent. By means of a lever (leverage) function with the protrusion contacting the back surface of the support member as a fulcrum, the holding portion moves in a direction approaching the plate member. Therefore, in this electric wire fixing structure, as in the conventional case, if the insertion portion inserted into the through hole of the plate member is bent, the holding portion surely comes into pressure contact with the plate member via the electric wire. This can solve the problem of poor fixing of the electric wire.
