In addition, it is possible to flexibly cope with the bottom of a vehicle having a different shape (that is, the place where bolts can be attached is different).

As shown in FIG. 5, the T-type protector 2a further includes a branch portion 6 that branches from the main body portion 3. In the T-type protector 2a of FIG. 5, the wire harness 1 is guided along a path having no curved bend when viewed in the width direction of the single protector 2. Therefore, the T-type protector 2a is a flat-type protector. Further, the wire harness 1 is guided along a branched path. Therefore, the T-type protector 2a is a branched protector.

The branch portion 6 is formed so as to extend perpendicularly to the main body portion 3, for example. However, the present invention is not limited to this, and the branch portion 6 may be formed so as to branch obliquely with respect to the main body portion 3.

The branch portion 6 includes a bottom portion 30, a first wall 31, and a second wall 32, similarly to the main body portion 3. Since the configurations of the bottom portion 30, the first wall 31, and the second wall 32 in the branch portion 6 are the same as those of the main body portion 3, detailed description thereof will be omitted. The above-mentioned partition portion 34 is provided on the tip end side (the side away from the main body portion 3) of the branch portion 6. Then, at the tip of the branch portion 6, an auxiliary connecting portion 52 further extending from the bottom portion 30 of the branch portion 6 is provided. At the tip of the branch portion 6, a second connecting portion 51b is provided on the outside of the first wall 31 and the second wall 32. That is, the branch portion 6 includes a part of the above-mentioned connection structure 5.

Since the configurations of the partition portion 34, the auxiliary connecting portion 52, and the second connecting portion 51b in the branch portion 6 are the same as those of the main body portion 3, detailed description thereof will be omitted.

The branch portion 6 configured as described above can be connected to the first connecting portion 51a included in the other single protector 2.

The crank type protector 2b has substantially the same configuration as the above-mentioned flat type protector. As shown in FIG. 6, the crank type protector 2b includes a crank type main body portion 3b. The crank type main body 3b is different from the main body 3 of the single protector 2 of FIG. 2 in that the crank type main body 3b is formed in a crank shape when viewed in the width direction of the single protector 2. By using the crank type protector 2b, the shape of the harness protector 100 can be made to follow the step formed on the bottom of the vehicle.

In the crank type protector 2b of FIG. 6, the wire harness 1 is guided along a path having a curved bend when viewed in the width direction of the single protector 2. Therefore, the crank type protector 2b is a step type protector. Further, the wire harness 1 is guided along a non-branched path. Therefore, the crank type protector 2b is a non-branched type protector.

With respect to the wire harness 1, the single protector 2 formed as described above is attached to the wire harness 1 as shown in FIG. 7. Since the plurality of single protectors 2 are separated from each other, the wire harness 1 can be bent so as to swirl and accommodated in the packing box 90. As a result, the packaging can be made very compact. Therefore, a small packing box 90 can be used, and the transport efficiency can be improved.

When the wire harness 1 housed in the packing box 90 of FIG. 7 is routed to the bottom of the vehicle, two single protectors 2 adjacent to each other in the longitudinal direction of the wire harness 1 are connected to each other via a connecting portion 51. , Lock. After that, the strength of the connecting portion of the two single protectors 2 can be increased by winding the adhesive tape 9 around the auxiliary connecting portion 52 as shown in FIG.

The harness protector 100 of the present embodiment is realized by combining and connecting small single protectors 2. Therefore, as compared with the case of forming a large one-point protector, this harness protector 100 changes the number of connected single protectors 2 or is connected even if the shape of the bottom of the vehicle is changed.
