Description of the Related Art Conventionally, in a wire harness of an automobile, as shown in FIGS. 5A and 5B, a terminal of a branch line 2 branched from a main line 1 of a wire harness W / H in order to provide a join circuit. In many cases, the joint connector 3 is connected to the joint connector 3, and the joint connector 3 is fixed by winding the tape 5 around the trunk line 1a.

On the other hand, in order to fix the wire harness W / H to the vehicle body, a belt clamp 4 (or a board type clamp) is attached to the trunk line 1.

[0004]

The above-mentioned belt clamp 4
Since the blade-shaped vehicle body locking portion 4a that serves as the clamp body is inserted and locked in the vehicle body locking hole, the vehicle body side direction (see FIG.
It is necessary to attach it in the direction (A) in (B). On the other hand, if the joint connector 3 mounted near the belt clamp 4 is mounted on the trunk line 1 in the direction A on the vehicle body side, the joint connector 3 interferes with the vehicle body. It is necessary to set the vertical B direction or the C direction opposite to the A direction.

At the time of assembling the wire harness, the locking blade portion 4a of the clamp 4 is directed in the A direction, and the joint connector 3

Due to the twist of H and the loosening of the tape 5 fixing the joint connector 3, the joint connector 3 may face the vehicle body side in the same direction A as the vehicle body engaging portion 4a of the clamp 4, as shown in FIG. Especially for belt clamps,
The band may rotate, and the vehicle body engaging portion 4a and the joint connector may be oriented in the same direction.

As described above, when the positional relationship between the vehicle body engaging portion 4a of the clamp and the joint connector 3 deviates from the setting,
It becomes difficult to attach the wire harness W / H to the vehicle body. In order to eliminate this problem, the mounting position of the clamp 4 and the mounting position of the joint connector 3 need to be separated from each other with a large dimension, but the mounting interval of the clamp 4 is small and the mounting position of the clamp 4 and the joint connector 3 is small. In some cases it may not be possible to leave a large distance between positions.

The present invention has been made in view of the above problems, and an object of the present invention is to allow the clamp to be held as designed without any displacement in the positional relationship between the vehicle body engaging portion and the joint connector.
