In Patent Document 1, no consideration is given to the alignment of the binding positions of the additional wire harnesses 101 and 102 with respect to the binding component 104 (band clamp) attached to the main wire harness 100. Therefore, for example, when the clamps are attached to other positions of the additional wire harnesses 101 and 102, after these clamps are locked to the vehicle body, the positions of the clamp 104d of the binding component 104 and the locking holes of the vehicle body are set. Misalignment is likely to occur.
Further, when the additional wire harnesses 101 and 102 are attached, there is no portion for supporting these additional wire harnesses, and the additional bundling work cannot be easily performed.

  The present invention has been made in view of the above problems, and enables easy and reliable positioning of the additional wire harness with respect to the main wire harness, so that the clamp attached to the wire harness is a locking hole for clamp attachment on the vehicle body side. It is an object of the present invention to prevent misalignment and to make it easy to attach an additional wire harness.

In order to solve the above-described problems, the present invention provides a rectangular main harness mounting portion, an additional harness mounting portion protruding from a side edge in the width direction orthogonal to the length direction of the main harness mounting portion, and the main harness A board-type clamp that integrally molds the clamp for locking the vehicle body that protrudes from the back surface of the central portion in the length direction of the mounting portion is provided,

The additional harness mounting portion is at a position corresponding to a clamp projecting from the central portion in the length direction of the main harness mounting portion. Therefore, when the tape is wound around the main harness mounted on the main harness mounting portion at the position along both side edges in the length direction of the additional harness mounting portion, the position where the clamp is sandwiched becomes the tape winding position. By aligning the tape position of the additional harness with the winding position of the tape, the additional harness can be accurately aligned and bundled with the main harness. Therefore, it is possible to prevent the clamping position of the board-type clamp attached to the main harness from being displaced from the locking hole on the vehicle body side.

  When an additional harness mounting part is provided only at one side edge of the main harness mounting part, if the clamp protrudes from the center of the back surface of the main harness mounting part, the clamp is not positioned at the center in the width direction, and is biased to one side. Preferably, the clamp is provided between the main harness mounting portion and the central portion of the additional harness mounting portion, and the clamp is positioned at the center in the length direction and the width direction of the substrate.

The board-type clamp is provided with two additional harness mounting portions from both side edges of the main harness mounting portion, and one flat plate protruding from one side edge of the central portion in the length direction of the main harness mounting portion is One additional harness mounting portion, and two flat plates protruding from both sides in the length direction of the other side edge of the main harness mounting portion are used as the second additional harness mounting portion.
