抵抗できる大きな電線等の保持力が求められている。Generally, when an electric wire is attached to a vehicle body, it is required that the electric wire be as close as possible to the vehicle body. Therefore, it is desirable to make the locking claw portion of the buckle small. However, when the locking claw portion is reduced, the rigidity of the locking claw is reduced, and the locking claw portion is weakened.
The holding power of electric wires etc. decreases. In order to increase the holding force of the electric wire or the like, the number of locking claws was simply increased to a plurality, but the pulling resistance after locking the band could not be sufficiently increased. In the process of assembling a car, an electric wire attached along a vehicle body having a complicated structure may be strongly pulled during the assembling work, and a holding force for a large electric wire or the like that can sufficiently withstand a pulling force is required. .

One ratchet claw engaged with the locking claw pulls the locking claw to deform the portion where the locking claw is provided, and the interval between the adjacent locking claw is increased, so that the adjacent ratchet claw corresponds. And the pull-out force of the band is distributed to the two locking claws. For this reason, the pull-out force is not concentrated on one locking claw but is distributed to at least two locking claws, so that the pull-out resistance of the band is at least doubled. Therefore, without using high rigid material such as metal for the locking claw of the band, by molding plastic,
High holding power can be exhibited.

The band 5 is formed smaller than the interval between the ratchet claws 14, that is, the pitch. In the experiment, the ratchet nail 14
Is 1.3 mm, the pitch between the first locking claw 21 and the second locking claw 22 is 1.2 mm. Further, the number of locking claws of the buckle portion 6 may be three or four as long as it is two or more. Also in this case, the interval between the locking claws, that is, the pitch, is formed so as to be smaller than the pitch of the ratchet claws 14. The distance between the locking claws is such that when a strong pulling force is applied to the band 5, one ratchet claw engaged with one locking claw pulls the locking claw to extend the cantilevered support arm portion. The spacing is selected such that the spacing between adjacent pawls is increased by deformation so that another ratchet pawl engages the corresponding adjacent pawl. Thereby, the pull-out force of the band 5 is
It is distributed to at least two locking claws, and the load on each locking claw is reduced.

On the ratchet claw 14a and the adjacent ratchet 14b. Now, arrow 29 on band 5
When the pulling force in the direction shown in FIG.
Is strongly in contact with the opposing surface of the second locking claw 22 and the second locking claw 2
2 is stressed. Due to the stress on the second locking claw 22, a force deforming in the direction of the arrow 30 acts on the portion of the cantilever support arm 19 to lift the second locking claw 22 in the direction of the arrow 30. Due to this deformation, the interval between the second locking claw 22 and the first locking claw 21 is widened, and the surface of the first locking claw 21 is inclined to approach and abut the adjacent ratchet claw 14b. By this contact, the pull-out force of the band 5 is also applied to the first locking claw 21. As a result, the pulling force of the band 5 can be reduced not only by the second locking claw 22 but also by the first locking claw 22.
In addition to the locking claws 21, the pull-out force is distributed to at least two locking claws without being concentrated on one locking claw. This will increase the pull-out resistance of the band at least twice. If the number of locking claws is increased at a pitch smaller than the pitch of the ratchet claws 14, the pull-out resistance can be further increased.

れることがわかった。On the other hand, as shown in FIG. 6, the pitch between the first locking claw 26 and the second locking claw 27 is
When the pitch a and the pitch of the ratchet claw 14b were the same, the following problems were observed. When a pulling force is applied to the band, the second locking claw 27 and the first locking claw 26 simultaneously engage with the ratchet claw 14a and the ratchet claw 14b, and stress is applied to both locking claws. By the way, as described above, since the stress applied to the second locking claw 27 acts to deform the cantilever support arm 19, the first locking claw 26 is also deformed and tilted, thereby causing the first locking claw 26 to tilt with the ratchet claw 14b. It was found that the engagement was released. In another case, the second locking claw 27 is deformed against the ratchet claw 14a, the deformation of the first locking claw 26 is increased, and the stress is concentrated on the ratchet claw 14b. The engagement between the claw 14b and the first locking claw 26 has been released. In still another case, the first locking claw 26 and the second

ることができる。According to the fastener of the present invention, at least two locking claws are provided on the buckle portion, and the spacing, that is, the pitch between the locking claws is set smaller than the spacing, that is, the pitch between the ratchet pawls of the band. So that when a pulling force is applied to the band,
The two ratchet pawls pull the locking pawls to deform the portion where the locking pawls are provided, so that the distance between the adjacent pawls increases, and the adjacent ratchet pawls engage with the corresponding adjacent pawls. Then, the pulling force of the band is distributed to the two locking claws. For this reason, the pull-out force is distributed to at least two locking claws without concentrating on one locking claw, so that the pull-out resistance of the band increases at least twice, and metal A high holding force can be exhibited by molding plastic without using a highly rigid material such as made of plastic.
