DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clamp for fixing a wire harness, which is routed to an automobile, to a vehicle body, and more particularly, to insert a locking portion of the clamp attached to the wire harness into a locking hole provided on the vehicle body. When the wire harness is attached to the vehicle body by locking, the clamp is detached from the locking hole so that the wire harness can be easily removed from the vehicle body.

[0002]

2. Description of the Related Art A band-type or board-type clamp is mounted in advance on a wire harness routed along a vehicle body (vehicle body) at a required position, and a wing-shaped engaging portion of the clamp is attached to the vehicle body. The wire harness is fixed to the vehicle body by being pushed into the locking hole formed in the vehicle body.

In recent years, the necessity of separate disposal and recycling of automobile parts and materials has been increasing, and the above-mentioned clamps can not only securely fix a wire harness to a vehicle body, but also easily remove them from the vehicle body as necessary. There is a need to be able to remove and recycle.

However, in the above-described general clamp, in order to remove the clamp from the vehicle body, it is necessary to release the lock by bending the locking portion inward with a finger to get out of the locking hole. Actually, however, it is difficult for the wire harness to hinder the bending of the locking portion of the clamp inward, and once the clamp is attached to the vehicle body, it cannot be removed.

Japanese Patent Laid-Open Publication No. 7-23937 discloses a structure in which a clamp can be removed from a body.
Clamps shown in (A), (B) and (C) have been proposed.
The clamp includes a clamp member 1 having an upright locking portion 1a,
Attachment member 2 to be fixed to the wire harness W / H by tape winding
Are separately provided, and the pawl 1a of the clamp member 1 is engaged with the elastic engagement piece 2a of the mounting member 2 and combined. When the wire harness W / H attached to the vehicle body is removed from the vehicle body via the clamp, the elastic locking piece 2a is pushed down to release the engagement between the mounting member 2 and the clamp member 1, and the wire harness W / H is mounted. It has been removed together with the member 2 from the vehicle body.

[0006]

When the wire harness is removed from the vehicle body, the clamp cannot be removed unless the free end of the elastic locking piece 2a of the mounting member is pushed down. And it is very difficult to push down the elastic locking piece 2a.

Further, even if the mounting member 2 is separated from the clamp member 1 and the wire harness is removed from the vehicle body, the clamp member 1 remains on the vehicle body side, which hinders recycling on the vehicle body side.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to allow a clamp to be easily detached from a vehicle body so that a wire harness can be removed from the vehicle body.
