  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<First Embodiment>
1 is a plan view showing an embodiment of a linear body mounting structure according to the present invention, FIG. 2 is a sectional view of the linear body mounting structure shown in FIG. 1 taken along line II-II, and FIG. It is the perspective view of the offset clamp used for the attachment structure of a linear body, Comprising: The figure (upper figure) looked down diagonally forward, and the figure (lower figure) looked down diagonally back.

  In the attachment structure 1, as shown in FIGS. 1 and 2, a wire harness (linear body) 3 is attached to a vehicle body (attached member) 2 with a synthetic resin band clip 5. In addition, an offset clamp 7 made of synthetic resin is attached to a portion around which the band clip 5 is wound.

  Here, as shown in FIG. 2, the band clip 5 has a structure in which a band portion 52 and a leg portion 53 are integrally connected to a base portion 51. The wire harness 3 and the offset clamp 7 are gripped by the band portion 52 of the band clip 5, and the leg portion 53 of the band clip 5 is fitted into the clip mounting hole 21 of the body 2.

  Moreover, the offset clamp 7 has the block-shaped main body 71, as shown in FIG. The main body 71 has a hole-shaped band insertion portion 72 formed on the back surface thereof, and two corrugated engagement protrusions 73 formed in an arc shape on the front surface. The band portion 52 of the band clip 5 is inserted into the band insertion portion 72 of the offset clamp 7. Further, a corrugated tube (not shown) is fitted to the outer periphery of the wire harness 3, and this corrugated tube is engaged with each corrugated protrusion 73 of the offset clamp 7.

  The width D2 of the offset clamp 7 is about twice or more the interference amount D3 (see FIGS. 7 and 8) between the wire harness 3 and the other component 6.

  When completing the attachment structure 1 having such a configuration, the wire harness 3 is attached to the body 2 according to the procedure described below.

  First, an offset clamp 7 is attached to the wire harness 3. To do so, the offset clamp 7 is applied to the corrugated tube in a state where the corrugated tube is fitted and taped to the outer peripheral portion of the wire harness 3. At this time, each corrugated protrusion 73 of the offset clamp 7 is engaged with the corrugated tube. Then, the position shift of this corrugated tube and by extension the wire harness 3 can be prevented.

  Next, the band clip 5 is wound around the wire harness 3 and the offset clamp 7. At this time, the band portion 52 of the band clip 5 is inserted into the band insertion portion 72 of the offset clamp 7.

  Finally, the band clip 5 is fixed to the vehicle body 2. For this purpose, the leg 53 of the band clip 5 is inserted into the clip mounting hole 21 of the body 2.

  Here, the attachment work of the wire harness 3 is completed, and the attachment structure 1 is completed.

  In this mounting structure 1, as shown in FIG. 2, the axis CT <b> 1 of the wire harness 3 is shifted to the opposite side of the offset clamp 7 by an offset amount D <b> 1 corresponding to the width D <b> 2 of the offset clamp 7. Therefore, even if it does not change the attachment position of the band clip 5, the situation where the wire harness 3 interferes with the other components 6 can be avoided.

  At this time, the offset amount D1 is about half of the width D2 of the offset clamp 7 regardless of the diameter of the wire harness 3, so that the amount of interference D3 between the wire harness 3 and the other component 6 is about twice or more. By using the offset clamp 7 having the width D2, it is possible to reliably avoid interference with other components 6. Accordingly, if a plurality of types of offset clamps 7 having different widths D2 are prepared and the width D2 of the offset clamps 7 is appropriately selected according to the interference amount D3, unlike the known technique 1, the offset amount D1 of the wire harness 3 is set. Fine adjustment is facilitated.

  Further, when the wire harness 3 is offset, it is only necessary to attach the offset clamp 7 to the wire harness 3 as described above. Therefore, unlike the known technique 2, not only the number of parts is small and the structure is simple, but also it can be dealt with according to the necessity of offset of the wire harness 3, and therefore it is excellent in versatility. Furthermore, since the conventional band clip 5 can be used as it is, it is highly practical.

  At this time, as shown in FIG. 5, a groove-shaped band insertion portion 72 may be employed. In this case, when the band clip 5 is wound around the wire harness 3 and the offset clamp 7, it is not necessary to insert the band portion 52 of the band clip 5 into the band insertion portion 72 of the offset clamp 7. Can be executed quickly.

  Further, as shown in FIG. 6, taping blades 74 may be formed on both the left and right sides of the main body 71 so as to extend, and a flange 75 may be formed at the tip of each taping blade 74. In this case, the rigidity of the wire harness 3 can be increased by the taping blades 74. In addition, the taping blade 74 is reinforced by the flange 75, and at the same time, the taping range becomes clear.
