Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a harness fixing structure for fixing a wire harness housed in a protector made of synthetic resin and having a U-shaped cross section.

[0002]

2. Description of the Related Art As a wiring duct to which this type of conventional harness fixing structure is applied, there is one disclosed in Japanese Utility Model Laid-Open No. 6-29326 shown in FIGS.

A wiring duct 1A shown in FIG. 10 has a U-shaped cross section and is elongated in one direction, and has a bottom wall 2 and left and right side walls 3 and 3 standing upright from both end sides thereof. The harness accommodating chamber 4 is formed inside by being surrounded by these.
The upper surface side of the harness accommodating chamber 4 has an opening 5 along the longitudinal direction. Further, the left and right side walls 3, 3 are provided with pressing rods 6, 6 projecting toward the center of the opening 5 so as to face each other.

In the above structure, the wire harness (not shown) is housed in the wiring duct 1A by the operator pushing the pressing rods 6 and 6 on both sides to open them and opening the pressing rods 6 and 6 on both sides to open them. The wire harness is inserted into the harness accommodating chamber 4 from 5. When the insertion of the wire harness is completed, the pressing rods 6 and 6 on both sides are released from the forced bending, whereby the pressing rods 6 and 6 on both sides return to their original positions by elastic return deformation.

The wire harness accommodated in the harness accommodating chamber 4 is prevented from coming out of the opening 5 due to the interference of the holding rods 6 and 6 on both sides, and the subsequent wiring work can be carried out smoothly. And so on.

In the wiring duct 1B shown in FIG. 11, the holding rods 6 and 6 on both sides are changed to flat holding plates 7 and 7 on both sides as compared with the wiring duct 1A. Also in this wiring duct 1B, the wire harness can be accommodated in the harness accommodating chamber 4 by the same operation as described above, and the wire harness can be prevented from protruding to the outside by the pressing plates 7, 7 on both sides. It is like this.

[0007]

However, in the above-mentioned conventional harness fixing structure, when the wire harness is housed, the worker holds the pressing rods 6 and 6 and the pressing plates 7 on both sides.
Since it is necessary to push open 7 and insert the wire harness in the pushed open state, the accommodation work is complicated.

Further, the wire harness accommodated in the harness accommodating chamber 4 is restricted from protruding to the outside by the pressing rods 6 and 6 and the pressing plates 7 and 7 on both sides, but is movable in the harness accommodating chamber 4. Since it was loose, the wire harness collided with the side walls 3 and 3 and the bottom wall 2 and generated abnormal noise.

Therefore, the present invention has been made to solve the above-mentioned problems, and the work of accommodating the wire harness in the harness accommodating chamber can be easily performed, and an abnormal noise due to rattling of the wire harness is generated. An object of the present invention is to provide a harness fixing structure capable of reliably preventing the occurrence.
