Description

[0001]
[Industrial application fields]
The present invention relates to a clip for holding a harness, cable, hose or the like that is routed in a closed cross-section such as a rear gate frame or pillar of a vehicle.
[0002]
[Prior art]
For example, as shown in FIG. 3, the harness b routed in the closed cross section of the rear gate frame a of the vehicle cannot be fixed in the closed cross section, so that the harness b is closed when the rear gate is opened or closed or during traveling. When the harness vibrates in the part and the harness is hardened, such as in cold weather, the hardened harness b may hit the inner surface of the closed cross-sectional part and generate a rattling sound. Conventionally, the occurrence of a rattling sound is generally prevented by winding a urethane tape c around the outer periphery of the harness b.
[0003]
Recently, as disclosed in Japanese Utility Model Laid-Open No. 2-91047, a large number of elastic needle-like protrusions having a spherical head formed at the tip are projected on the entire outer periphery of a headband-like clip body for bundling a harness. By using the clip of the provided structure and fitting the clip body to the harness and pulling it around the closed cross section, a large number of needle-like projections of the clip elastically contact the inner surface of the closed cross section, There has been devised one that is held substantially at the center, thereby preventing the occurrence of the above-mentioned rattling sound.
[0004]
[Problems to be solved by the invention]
The conventional soundproofing means for wrapping urethane tape around the harness requires the urethane tape to be attached to almost the entire length range of the harness in the closed cross section. There is a problem that the soundproofing effect is almost lost due to deterioration or peeling due to secular change.
[0005]
In addition, the special clip structure disclosed in Japanese Utility Model Laid-Open No. 2-91047 is a structure in which a large number of needle-like projections are radially projected on the entire outer periphery of the headband-shaped clip body, so that the formation is troublesome. In addition to being expensive and cumbersome to handle, there is a problem in that it is necessary to manufacture clips suitable for each of the various harness diameters and closed cross-section sizes, which incurs material costs. .
[0006]
The present invention aims to address the above-described conventional problems.
[0007]
[Means for Solving the Problems]
The present invention relates to a coil part having a holding clip such as a harness that is routed and disposed in a closed cross section of a rear gate frame or a pillar of a vehicle, and a coil part having means for fixing to the harness or the like, and outward from the coil part. Consists of a spring wire material in a shape having two arm portions that elastically contact with the opposing inner surfaces of the extended closed cross-section portion, and wire passage holes formed at the tips of the two arm portions, respectively. It is characterized by that.
[0008]
[Action]
The clip constructed as described above is attached and fixed to a harness or the like at its coil portion, the two arm portions are bent, the holes are matched, and the two arm portions are bent by passing the wire through the holes.
