The center C of the branch portion S of the linear body bundle W is connected to, for example, a body panel (external member) of a vehicle (not shown).
Used to fix to In addition, at the branch destination W2 of the wire harness W, a protective tube (vinyl tube or corrugated tube) T is close to the branch portion S so as not to be affected by the outside, for example, 10 to 20 mm from the surface of the branch source W1. The tube T is also covered to a position separated by a distance L of the order (the tube T may be covered also on the branch destination W3 side).

The binding band 10 is integrally formed in a T-shape from a flexible resin material, and is made thin enough to be able to be bent during the binding operation. The binding band 10 has a first band portion 11 extending in the lateral direction of the T-shape, and has an engagement groove 12 formed at one end thereof and extending in the extension direction thereof, and the other end thereof has one end thereof inserted therethrough. There is provided a locking portion 13 having an engaging claw (not shown) formed therein for locking the movement in the direction of engaging with the engaging groove 12 and returning when inserted into the hole 13a. A second band portion 16 of the binding band 10 extended in the T-shaped longitudinal direction has one end side of the first band portion.
An insertion portion 17 is provided at the other end of the first band portion 11 and has an insertion hole 17a formed through the one end of the first band portion 11 so as to be orthogonal to the engagement portion 13. The insertion portion 17 may be formed so that one surface of the insertion hole 17a is defined by an extension surface of the second band portion 16, as shown in FIG.

Reference numeral 21 denotes a moving guide.
A clip 22 is erected on one side of the surface 21 and elastic pieces 23 are formed on both sides thereof so as to bend upward on one side. On the other side, the other side of the second band portion 16 is formed. A guide portion 24 is formed in the shape of a hand of a key so as to face and engage with both sides of the key. The moving guide 21 can position the second band portion 16 between the guide portions 24 by a notch 16a formed in a portion close to the insertion portion 17 so as to correspond to the guide portion 24. And is movably held in the extension direction.

When the clip 22 is inserted from the head into a mounting hole opened in the body panel of the vehicle, the moving guide 21 abuts when the pair of flexures 22a, which expand in an arrow shape, are elastically deformed and return to their original shapes. The portion 22b engages with the mounting hole, and the elastic piece 23 is inserted when the clip 22 is inserted into the mounting hole.
Abuts on the surface of the panel and is elastically deformed, so that the panel can be sandwiched and fixed together with the clip 22, and the binding portion 10 is fixed by engaging and holding the guide portion 24 with the second band portion 16. I do. That is, the moving guide 21 constitutes a moving member, and the clip 22 and the elastic piece 23 constitute fixing means.

First, the binding band 10 with the moving guide 21 attached is prepared, and as shown in FIG. 6, the first band is attached to the branch source W1 close to the branch portion S of the wire harness W shown in FIG. In addition to positioning the portion 11, the moving guide 21 is positioned at the center position C of the branch portion S. At this time, since the movement guide 21 can be freely moved in the extension direction of the band portion 16, it can be positioned at any position regardless of the outer diameter of the wire harness W or the like. The illustration of the tape winding is omitted in the wire harness W after FIG.

Next, the insertion portion 17 of the second band portion 16 is turned to the opposite side (back side), and the first band portion 11 is wound around the branch source W1, and as shown in FIGS. After one end of the first band portion 11 is inserted into the insertion hole 17a of the insertion portion 17, the band portion 11 is further inserted into the insertion hole 13a of the locking portion 13 to lock the engagement groove 12, thereby tightening and binding. At this time, since the second band portion 16 is merely wound in the extending direction of the branch source W1, the tube T on the branch destination W2 side does not hinder the tightening. Further, since the insertion claw such as the locking portion 13 is not formed in the insertion portion 17, the first band portion 11
Can be inserted without resistance. In addition, travel guide
Since the guide portion 24 is pressed to the center position C by the second band portion 16 being wound around and tied to the branch portion S, the second band portion 21 does not move after the work. The excess of the first band portion 11 locked by the locking portion 13 is cut after this binding operation.

Thereafter, the binding band 10 can be fixed by the clip 22 and the elastic piece 23 by inserting the clip 22 from the head into the mounting hole of the body panel, and the wire harness W is connected to the center C of the branch portion S. Can be fixed. As described above, in the present embodiment, the branch source W1
In the wire harness W branched to the branch destinations W2 and W3, the second band portion 16 is turned to the opposite side through the center C of the branch portion S, and the first band portion 11 wound around the branch source W1 is engaged from the insertion portion 17. By inserting and locking the stopper 13, the binding can be performed regardless of the tubes T on the branch destinations W <b> 1 and W <b> 2.

At this time, the moving guide 21 is connected to the second band portion.
16 can be moved in the extension direction, and the position can be held and fixed at that position when the first and second band portions 11 and 16 are bound.
Of the wire harness W can be fixed to the panel of the external member. Therefore, the mounting state and dimensional accuracy of the wire harness W can be stabilized, and
Usability can be improved.

As another aspect of the present embodiment, although not shown, the engaging groove 12 is formed on the entire surface of the first band portion 11.
The first band portion 11 is configured so as to be movably held by a moving guide provided at one end of the second band portion 16. With such a configuration, the distance between the second band portion 16 and the locking portion 13 can be adjusted, so that a change in the outer diameter of the wire harness W can be more widely accommodated.

Further, the engagement groove 12 may be formed in the second band portion 16 and the insertion portion 17 may be provided in an engagement portion which can be engaged with the engagement groove 12. With this configuration, the tightening position of the first band portion 11 can be adjusted by adjusting the length of the second band 16. At this time, the engagement groove of the second band portion 16 or the first band portion 11 is formed in the moving guide 21 or the insertion portion 17 on which the clip 22 is erected.
Needless to say, an engaging claw that can be locked may be provided at 12 to enable positioning.

In the above embodiment, the clip 22 is erected on the moving guide 21 so as to be movable. However, the position of the clip 22 with respect to the first band portion 11 is determined by the second band portion. Needless to say, it may be provided by being integrally molded with the 16. Also, the first and second band portions 11,
It is needless to say that the 16s may be connected not only at right angles but also at an arbitrary angle.
