Restricts the band portion 3 from moving in the returning direction by engaging with the engagement groove 2 so that the band portion 3 does not come off. Is engaged with the edge of the mounting hole H so as not to come off.

[0005] In recent years, it has been required to separate and reuse members instead of discarding products as they are, and the wire harness W attached to the body panel B of the vehicle body is also removed from the panel B at the time of disassembly. Must be removed. For this reason, the binding band 1 is cut by inserting a blade of a cutting tool such as scissors or nipper between the band portion 3 and the wire harness W.

However, this operation must be performed for each binding band 1, and since the band portion 3 is in a state where the wire harness W is tightened, there is a problem that the operation takes a long time. Therefore, the present invention realizes easy breakage of the band portion without using a cutting tool, so that a member such as a wire harness which is bound and attached can be easily removed, and such as a disassembling operation. The purpose is to reduce the burden.

In order to achieve the above object, according to the first aspect of the present invention, there is provided an elongated flexible band portion and an inverted portion provided at an end of the band portion. A binding band comprising: a locking portion that engages with the band portion to lock the movement; and a fixing portion that is located on the outer surface side of the band portion and fixed to the attached member when the locking portion is engaged. Further, a break portion having a reduced cross-sectional area in the width direction of the band portion is formed in one or both side band portions near the fixing portion.

According to a second aspect of the present invention, in addition to the configuration of the first aspect, a perforation is provided in the width direction of the band portion as the breaking portion.
According to the first and second aspects of the present invention, the band portion near the fixing portion is formed to be thin or perforated, and extends through the broken portion having a reduced cross-sectional area in the width direction. The fixing portion fixes the member to be bound via the broken portion. Therefore, when an excessive load is applied to the band portion, the load is concentrated at the breaking portion and the band portion is broken, so that the banding can be released.

According to a third aspect of the present invention, in addition to the configuration of the second aspect, a step extending in the width direction is formed in the band portion, and a perforation is formed in the middle of the step. It is characterized by having. According to the third aspect of the present invention, the band portion extends through the perforation provided in the middle of the step near the fixing portion, and the perforation extends in a direction away from the fixing portion. Can be Therefore, the perforation tears in a direction to separate the bound member from the fixing portion.

[0010] The invention described in claim 4 is the invention according to claims 1 to 3.
In addition to the configuration of the invention described in any one of the above, the fixing portion is supported by a support portion extending to a vicinity of a broken portion. In the invention according to claim 4,
A support portion of the fixed portion is formed up to the vicinity of the break portion. Therefore, the deformation of the band portion between the support portion and the break portion is reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. 1 to 3 are views showing an embodiment of a binding band according to the present invention. In the present embodiment, the same components as those of the above-described related art are denoted by the same reference numerals, and description thereof will be simplified.

In FIG. 1, reference numeral 10 denotes a binding band made of a flexible resin material.
Is formed on one surface side of a band portion 3 wound around a wire harness (a member to be tied) W with an engaging groove 2 for engaging with a locking claw 4 when inserted into a locking portion 5 and a clip (fixing portion). Steps 11 are provided on both sides of the portion where the erecting member 8 is provided, and a protruding surface 12 that protrudes in the direction of the clip 8 is formed.

The clip 8 has a support portion 7 formed so as to extend in the direction of the step 11 on both sides of the projecting surface 12.
Are supported so as to intersect with the band portion 3. Also,
This band part 3 is perforated in the middle of the step 11 (fracture part).
13 are both inserted, and the connection area (cross-sectional area in the width direction) connecting the protruding surfaces 12 is reduced.
It is elongated through 13. In addition, this perforation
Needless to say, it is necessary to set 13 to such an extent that the wire harness W does not tear depending on a steady load such as vibration applied after fixing the wire harness W.

Therefore, as shown in FIG. 2, the binding band 10 is wound around a wire harness W formed by tape-winding the band portion 3 to lock the engaging groove 2, as in the binding band 1 described in the prior art. The wire harness W can be held in a tight state by removing the excess band portion 3 with scissors after the wire harness W is locked by the locking claw 4 of the portion 5. After that, FIG. As shown in FIG. 5, the end 7a of the bent portion 6 of the clip 8 is inserted into the mounting hole H of the panel B or the like shown in FIG. The rim can be engaged and fixed.

When a force (excessive load) is applied to the wire harness W to separate it from the panel B during the disassembly work of the vehicle body, the binding band 10 concentrates on the perforations 13 of low strength. With perforation 13
Because it is formed in the middle of 11, it tears in the direction of its load. At this time, the projecting surface 12 of the binding band 10 is
Since the supporting portion 7 extends to the vicinity of the step 11, its deformation can be reduced.

As described above, in this embodiment, the step 11 is formed on both sides of the clip 8 of the band portion 3 and the step 11 is formed.
When removing the wire harness W from the panel B at the time of disassembly or the like, when the wire harness W is removed from the panel B, the perforation 13 is broken by simply applying force to the wire harness W and pulling it apart. Accordingly, the band portion 3 can be broken, and the wire harness W can be easily removed from the panel B. At this time, the support portion 7 of the clip 8
As a result, the deformation of the protruding surface 12 of the band portion 3 can be reduced, so that the load can be effectively concentrated on the perforations 13 and the band portion 3 can be easily broken.

In this embodiment, the perforation is formed in the middle of the step. However, it is needless to say that only the perforation may be provided without providing the step. A thin portion formed thin in the direction may be formed, and the band portion may be broken at the thin portion.

[0018]

According to the present invention, since the band portion extends through a thin portion having a small cross-sectional area near the fixing portion or a break portion such as a perforation, the load is concentrated and the break portion is formed. Can be torn, and the band portion can be easily broken. Therefore, the band portion can be broken simply by applying a load so as to separate the tied member from the fixing portion without using a cutting tool, and the tied member can be easily removed. As a result, the work load at the time of dismantling or the like can be reduced.

At this time, by forming a perforation in the middle of the step of the band portion as a breakable portion, the perforation can be cut in a direction away from the fixing portion,
The perforations can be torn by a load that pulls the tied member away from the fixing portion. In addition, the band portion between the support portion and the break portion can be suppressed small deformation by extending the support portion to the vicinity of the break portion,
The band can be easily broken by effectively concentrating the load on the broken part.
