However, the clamp member 40 is fixed to the mounting means 4 by the temperature or vibration on the fixed side.
3 has problems such as falling off due to the weight of the wire harness 41, and the deterioration of the material is remarkably accelerated.

In addition, it is necessary to secure a large mounting space for the clamp member 50 on the fixed side, a large space for mounting work is required, and it is also necessary to prevent the wiring harness from being forgotten. There are problems such as forgetting to tighten the screws.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a clamp member for attaching a wire harness to a fixed side where high temperature and vibration are generated, to have heat resistance and vibration resistance, and to reduce the mounting space by achieving compactness. Another object of the present invention is to provide a clamp member capable of simplifying an attaching operation.

[0007]

SUMMARY OF THE INVENTION The object of the present invention is to provide a clamp member for holding the wire harness by sandwiching the outer periphery of a buffer member wound around the outer periphery of the wire harness, the clamp member being formed of a rigid body. A first clamp and a second clamp, wherein one end of the first clamp is provided with a locking projection, and one end of the second clamp is provided with a locking hole, And the above-mentioned locking hole portion constitutes a connecting portion. Further, the above object is achieved by providing the clamp member, wherein the other of the first clamps is provided with a set projecting piece cut and raised in a curved inward direction, and a set hole is provided below the second clamp. The present invention is solved by a clamp member in which a preset engaging portion is constituted by a projecting piece and the setting hole.

That is, in the clamp member having the above structure, a clamp member for clamping the wire harness via a shock-resistant material such as a vibration-proof rubber having heat resistance is formed by bending a substantially rigid body such as a metal material into a substantially arcuate shape. The clamp member is provided with a connecting portion and a preset engaging portion, and the two clamp members are provided with a connecting function and a preset function. Further, by being formed from a rigid body such as a metal material, it is possible to prevent the clamp member from falling off due to vibration or being deteriorated due to high temperature, even if it is attached to a high temperature and vibration generating portion. . Further, since the above configuration can be made compact, it can be mounted even in a place where the mounting space is small, and can be preset so that the mounting work is easy and the mounting work is simplified. be able to.
