Therefore, when an external force is applied in the axial direction of the wire harness and the adhesive tape attempts to move, the end surface of the adhesive tape comes into contact with one of the engaging protrusions, so the tape moves in the axial direction. is regulated, thereby preventing the wire harness from moving in the axial direction due to the external force.

(Example) An example of this invention will be described below with reference to FIGS. 1 to 4. The first one showing the fastener from the side.
In the figure and in FIG. 2, which is shown in a partially cut-away front view, the fastener made of synthetic resin material has a holding part 10 and a locking leg part 20.

The holding part 10 has the shape of a long thin plate bent into a substantially U-shape, and has upper and lower holding pieces 11 and 12 and a connecting piece 13 that connects both the holding pieces 11 and 12. The tips of both holding pieces 11 and 12 can be expanded against elasticity. Both holding pieces 1
Elastic bending pieces 14, 14 which are folded inwardly are provided at the tips of 1, 12.

A wedge-shaped engagement protrusion 15 is provided protruding from approximately the center of the inner side of one end (right end) of the upper holding piece 11 . Furthermore, a wedge-shaped engagement protrusion 16 is provided protruding from the inner one end (left end) of the lower holding piece 12 at approximately the center thereof. Therefore, both engaging protrusions 15,1
The distance A between the wire harnesses WH is formed to be slightly larger or approximately equal to the width B of the adhesive tape T wound around the wire harness WH (see FIGS. 2 and 3).

Further, the left and right engaging protrusions 15, 16 have a protruding height approximately equal to the winding thickness of the adhesive tape T, as shown in FIGS. 1 and 2.

The outside (lower surface) of the lower holding piece 12 of the holding part 10
The locking leg portion 20 provided in the center is connected to the holding piece 1
2, and a pressure receiving base 22 formed in the shape of a warhead at the lower end of the central shaft 21.
, left and right leg pieces 24 , 24 formed so as to form a substantially V-shape through thin-walled parts 23 , 23 on the left and right sides of the connection portion between the central shaft 21 and the pressure-receiving base 22 , and the upper ends of both leg pieces 24 , 24 . It consists of protrusions 25, 25 protruding from the top. By closing against elasticity, the leg pieces 24, 24 can be inserted into a mounting hole H formed in the body (fixed side member) BP of a vehicle such as an automobile.

An example of fixing the wire harness WH to the vehicle body BP using the above-mentioned fastener will be described with reference to FIG. 3. First, wire harness WH
An adhesive tape T is wrapped around the wire to have a predetermined width B, and a plurality of electric wires W to W are bundled. Then, attach the wire harness WH of the adhesive tape T part to the holding part 1.
While guiding between the bent pieces 14, 14 of both holding pieces 11, 12 of 0, press it toward the connecting piece 13. As a result, the space between the holding pieces 11 and 12 is expanded against the elasticity (see Fig. 4), and at the same time as the wire harness WH passes through the tips of the bent pieces 14 and 14, the space between the holding pieces 11 and 12 is expanded against the elasticity. Both holding pieces 11, 1
2 is restored to its original state, and the wire harness WH is held within the holding portion 10. Then, at the same time as the holding, the engaging protrusions 15 and 16 engage the wire harness WH.
With the adhesive tape T in between, its tip is inserted between the electric wires W and W of the wire harness WH.
Therefore, the wire harness
WH is an adhesive tape T between the engaging protrusions 15 and 16.
are placed so that the engaging protrusions 15 and 16 are held opposite the end surfaces of the adhesive tape T, respectively.

Next, the pressure receiving base 22 of the locking leg 20 is pushed into the mounting hole H of the vehicle body BP. As a result, the space between the left and right leg pieces 24, 24 narrows against the elasticity, and at the same time as the leg pieces 24, 24 pass through the mounting hole H, the elasticity causes the leg pieces 24, 24 to narrow.
is restored to its original state, and the protrusions 25, 25 are attached to the mounting holes H.
By coming into contact with the inside, the fastener is fixedly attached to the body BP in a manner that it cannot be removed, and the wiring of the wire harness WH is completed.
