DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on an embodiment shown in the accompanying drawings. 1 is a schematic perspective view showing a state where the harness mounting member 1 is mounted on the transmission T, FIG. 2 is a bottom view of the harness mounting member 1,
FIG. 3 is a partial cross-sectional view of the harness mounting member 1 as viewed from the bottom. FIG. 4 is a schematic diagram for explaining a mounting state of the harness mounting member.

FIG. 2 is a view showing a main part of a harness support structure according to this embodiment. The main part shown in FIG. Harness mounting member 1 for supporting wire harness
It is.

The harness mounting member 1 includes a binding portion 2 for binding a wire harness (indicated by W in FIG. 4 for convenience), and a binding portion 2 for attaching the binding portion 2 to a vertical mounting surface F described below. And an attachment portion 3.

In the case of the present embodiment, as shown in FIG. 4, a vertical portion is provided on the lower surface of the transmission T so as to be provided in the vehicle body or the engine room and to support the wire harness W. Is used. In the vicinity of the vertical mounting surface F, a rib R for securing rigidity is provided.

In FIG. 2, the binding portion 2 and the mounting portion 3 are formed by integral molding.
Is a known bendable band portion 2A and the band portion 2A.
And a locking portion 2B to which the tip of A is hooked. The binding portion 2 is bendable so as to surround the outer periphery of the wire harness, and its distal end is engaged and disengaged with a locking hook 2C provided on a locking portion 2B located at the base of the band. A plurality of possible protrusions 2D are formed, and a plurality of thin portions 2E are provided to reduce bending resistance.

The mounting portion 3 has a stem 5 provided on a base 3A and first and second stems 5 provided in different directions with respect to the stem 5 as shown in FIG. , Each of the restricting pieces 6 and 7 are provided.

The stem 5 stands upright from the base 3A and is formed in a direction parallel to the direction in which the wire harness extends, that is, in the direction of the center axis of the loop formed by the band portion 2A. Are provided with a plurality of tooth portions 5a, 5a which engage with the mounting holes 8 provided in the boss. That is, when the stem 5 is inserted into the mounting hole 8 of the vertical mounting surface F, the teeth 5a and 5a engage with the inner peripheral surface of the mounting hole 8 and are held so as not to be accidentally pulled out. .

As shown in FIG. 3, the first restricting piece 6 formed on the opposite side to the binding portion 2 with the stem 5 interposed therebetween has a direction perpendicular to the band width direction of the binding portion 2. The base 3A having a flat surface is formed to hang down at the end of the base 3A (see FIG. 2), and the lower surface of the rib R formed on the transmission T (see FIG. 4) in FIG. It is configured to abut against. That is, when the first restricting piece 6 comes into contact with the rib R of the transmission T, as shown in FIG. The attachment member 1 is restricted from rotating clockwise. The rib R corresponds to a fixing member described in the claims.

On the other hand, in the case of this embodiment, the second restricting piece 7 provided to be biased to the side of the mounting portion 3 is a base 3A on which the stem 5 is provided as shown in FIG. As shown in FIG. 2, it is formed of a frame-like member that encloses the stem 5 and has a central portion that is missing, as shown in FIG.

That is, since the second restricting piece 7 protrudes outward from the base 3A and is formed as a so-called overhang, the transmission T on which the stem 5 is mounted is mounted.
Side vertical mounting surface F can be opposed to the top surface,
A pair of reinforcing ribs 7A are provided at positions corresponding to both sides of the top surface of the second regulating piece 7 to reinforce the second regulating piece 7 formed in a frame shape. .

The second restricting piece 7 having such a structure is similar to that of FIG.
As shown in the figure, the vertical mounting surface F on the transmission T side
Is arranged near the top surface, but because of being located on the side continuously to the base 3A, the vertical mounting surface F is configured to be mounted only from one side, The mounting direction of the mounting member 1 with respect to the mounting surface F is defined.

Since a pair of the ribs 7A are formed on the second restricting piece 7 configured as described above, a certain level of strength can be maintained, and when an external force toward the stem 5 is applied, The external force can be absorbed by being deformed by the external force. Thereby, the external force on the stem 5 is absorbed and the external force in the direction of shearing the stem 5 is not applied, so that the breakage of the stem 5 can be reliably prevented.

Since the wire harness support structure according to this embodiment is configured as described above, when supporting the wire harness W, as shown in FIG. , From one side. That is, the second restriction piece 7 that is overhanging from the base 3A can be mounted in a state of being covered from one side of the vertical mounting surface F. Thereby, the harness mounting member 1
Since the mounting direction of the wire harness W is defined as a predetermined direction, the extending direction of the binding portion 2 is accurately positioned at the wiring position of the wire harness W. As a result, it is possible to reliably prevent an assembly error in which the relative position between the wiring position of the wire harness W and the band is on the opposite side.

Further, since the second restricting piece 7 is formed in a frame shape including the stem 5, the stem 5 can be formed directly by a mold through a frame, and the accuracy can be improved. Is improved.

In the harness mounting member 1 in which the mounting direction with respect to the vertical mounting surface F is defined, the stem 5 is pushed into the mounting hole 8 formed in the vertical mounting surface F so that the vertical It is mounted on the mounting surface F. That is, when the stem 5 is pushed into the mounting hole 8, the stem 5 engages with the inner peripheral surface of the mounting hole 8 inadvertently due to the direction of the teeth 5 a, 5 a depending on the direction of the teeth 5 a, and when the force is applied. It can be prevented from falling off.

When the stem 5 is completely pushed into the vertical mounting surface F, as shown in FIG. 4, the first restricting piece 6 contacts the rib R of the transmission T, and The second regulating piece 7 faces the top surface of the mounting surface F. When the first restricting piece 6 abuts on the rib R, the weight of the wire harness bound at the binding portion 2 can reliably restrict the harness mounting member 1 from rotating clockwise in FIG. The wire harness W can be held at the wiring position. That is, there is no fear that the wire harness W touches another member near the wiring position.

[0025]

As described above, according to the first aspect of the present invention, since the rotation of the wire harness bound by the binding portion due to the weight can be reliably prevented, the wire harness is connected to the wiring harness. There is no need to worry about touching other members near the position.

According to the second aspect of the present invention, in addition to the above-described effects, the stem can be formed directly by a mold through a frame, and the dimensional accuracy of the stem is improved. The attachment to the surface can be made more stable.
